Chapter 8: Piping Systems
About System Piping Revit provides tools for the creation, layout, and sizing of piping. It also includes different types of piping and pipe fitting families. Each family is a 3D representation of a pipe or pipe fitting and has the same characteristics as the actual physical components in the building. You can check piping modeled using Revit piping components for interferences with other systems and schedule the piping for quantity and analysis purposes.
System piping
Definition of System Piping, Pipe Fittings, and Pipe Systems System piping is a 3D representation of the sections of pipe to be used in the building mechanical systems. Pipe fittings are 3D representations of the connections and transitions among various sections of a pipe. Pipe systems are collections of piping and pipe fittings that are used to create piping of a particular type or for a particular purpose. When placing the pipe of a given pipe system, the pipe fittings used in the pipe type families specified in the type properties of that system are automatically inserted to create the piping run.
Lesson: Creating System Piping

The following illustration shows the type properties of PVC pipes.
Piping Element Properties Used in Sizing The pipe sizing tool uses certain piping element properties in sizing the pipe. The material of the pipe determines roughness, and the pipe fittings used in the pipe type family determine the algorithm to be used in sizing the pipe. The settings used for determining these properties for a given pipe run are available in the Pipe Type system family.
Methods for Pipe Sizing The pipe sizing methods are based on velocity, friction, or a combination of the two quantities. The following table describes the four pipe sizing methods.

■
Pipe Sizing Method
Description
Velocity
A pipe is sized based on the velocity specified in the Pipe Sizing dialog box.
Friction
A pipe is sized based on the allowable friction as specified in the Pipe Sizing dialog box.
Chapter 8: Piping Systems
Pipe Sizing Method
Description
Velocity and Friction
A pipe is sized to meet both the velocity and allowable friction specified in the Pipe Sizing dialog box.
Velocity or Friction
A pipe is sized to meet velocity or allowable friction as specified in the Pipe Sizing dialog box.
The following illustration shows the Pipe Sizing dialog box.
Piping Placement Tools The Place Pipe tab provides tools for placing the mechanical equipment to be piped and for placing the pipe, pipe fittings, and accessories such as the temperature gauge, flow meter, or air separator. When you activate the Pipe tool on the Plumbing & Piping panel of the Home tab, the Options Bar displays various options that you can use to place the pipe. You can specify various settings, such as the diameter, offset, elevation locking, level, and slope, prior to placing the piping in your Revit model.
Lesson: Creating System Piping
■
5
Pipe Slope Tool When inserting a pipe into your Revit model manually, you can specify a slope for that pipe on the Options Bar. However, you can also use the Generate Layout tool on the Layout panel of the Modify Mechanical Equipment tab. When doing so, you can again use the Slope option on the Options Bar to slope a pipe based on a total rise and run or with a specified rise per specified length of the pipe.
Automatically Connect The Automatically Connect option on the Placement Tools panel of the Place Pipe tab allows you to automatically connect to a run of pipe or a piping connector on mechanical equipment. To avoid connection at a location nearby or directly above a pipe run or mechanical equipment, you might need to deactivate Automatically Connect.
Example of a Piping System The following illustrations show various types of piping systems.

Process of Creating a Piping System A piping system associates two or more objects that are to be connected with piping and share common piping characteristics. This association of objects to be piped to a piping system provides information that you can use to size the required pipe and mechanical equipment. Assigning objects to a system also facilitates the use of the auto routing tools to quickly insert piping, connecting the objects that make up the system. You can create different types of piping systems, such as hydronic supply and return, sanitary, and domestic hot and cold water systems.
Process: Creating a Hydronic Supply Piping System The process of creating a hydronic supply piping system is shown in the following illustration.

Automatically route system piping by selecting Generate Layout on the Layout panel of the Modify Mechanical Equipment tab. Specify pipe main routing for the system and use the arrows on the Options Bar to cycle through potential routing solutions. Specify the liquid in the system. Specify the liquid in the system and the solution concentration, if appropriate, by selecting System Properties on the System Tools panel of the Piping Systems tab. Save the changes. Save the changes and finish creating the system.
Guidelines for Creating a Piping System The following recommended practices help you effectively create a piping system.
Guidelines ■

■
Select the appropriate pipe type for the pipe installation you have in mind. Using an incorrect pipe type for a given installation may result in actually installing the incorrect pipe type. Create hydronic systems to automate the process of pipe routing and track system data for sizing and analysis. This will improve the design, efficiency, and reliability of the overall mechanical system. Trim the pipes that intersect. The resultant pipes that terminate at the same location will insert the appropriate fitting automatically. This saves time because the proper fitting is placed automatically as a by-product of the trimming operation. Verify that sloped pipe systems are pitched in the desired direction after automatic pipe routing is complete. This is a sound practice for creating a piping system as you should never accept any automatic operation at face value.
Chapter 8: Piping Systems
Exercise: Create a Hydronic Return Piping System In this exercise, you create a hydronic return piping system. You are placing an air-cooled chiller outside the basement of a building.

Chapter 10: Fire Protection Systems
About Fire Protection Systems Using Revit, you can create, layout, and specify the size of a fire protection system and its components.
Definition of a Fire Protection System A fire protection system is a group of sprinklers and the supporting piping and valves required to create the system. You can create a sprinkler system by placing sprinkler heads, such as upright and pendent, as elements hosted in the ceiling or as nonhosted elements. You can then generate the sprinkler piping using the auto-layout tools or by manually drawing it. When using autolayout tools, you should set an elevation for the piping head. This is because the layout tools do not find a solution for piping at an elevation above upright heads or below pendent sprinklers. You can also check the fire protection system and its components for interferences with other components in a building. The information stored within the system can be used for analysis or scheduling purposes.

Sprinkler Libraries You can use a number of sprinkler families included in the sprinkler library folders by loading them into your project.
Partial listing of the available sprinkler families
Hosted families require a ceiling for placement, and nonhosted families require an elevation to be specified.
Sprinkler Tools You can use the various tools on the different panels of the Place Sprinkler tab to place sprinkler heads, sprinkler piping, and pipe accessories. When placing sprinklers, you should place the sprinkler piping above the pendent type sprinkler heads and below the upright sprinkler heads. This is because a piping run created in the opposite direction does not connect to the sprinkler as intended. The following illustration shows the panels on the Place Sprinkler tab.

■
Chapter 10: Fire Protection Systems
Wet and Dry Fire Protection Systems You can connect a sprinkler head to a wet or dry fire protection system. Sprinklers that are created for use in a dry sprinkler system can only be assigned to dry sprinkler systems and the same is true for wet sprinkler systems. When you create a new system from a sprinkler placed in a model, only the system, wet or dry, that corresponds to the sprinkler type is available as an option.
Example of a Fire Protection System The following illustration shows a 3D view of a typical run of sprinklers and associated piping.

Chapter 11: Electrical Systems
About Electrical Circuits You create electrical circuits to place electrical components, such as devices, lighting fixtures, and electrical equipment, in a project. You can connect components to a circuit using an available electrical connector if the components have correct electrical settings, such as voltage, number of poles, and phase.
Definition of Electrical Circuits Electrical circuits connect similar electrical components to form an electrical system. An electrical circuit is associated with a circuit number on a panel. You can define which components can connect to each other and track cumulative electrical loads as you add components to the circuit. You can use the electrical properties of components to populate a panel schedule, size wiring based on voltage drop, and balance loads across the panel.
Voltage Definitions Voltage definitions in Revit include a range of voltages that you can assign to the distribution systems in a project. Each voltage definition is specified as a range of voltages to allow for differing voltage ratings on devices from various manufacturers.
Distribution Systems Distribution systems in Revit define the characteristics of connected panels and circuits. Phasing, configuration, number of wires, and voltage definition information are defined within the distribution system.
Depending on your project requirements, you can edit, add, or delete voltage definitions and distribution systems.

Guidelines for Creating Electrical Circuits The following recommended practices help you create electrical circuits efficiently.
Guidelines In the initial stages of development, ensure that the distribution systems are defined appropriately as part of Electrical Settings for the application you design. Assign a distribution system to panels as well so that you can connect devices only to panels of the same distribution system. Include the light fixture ID, circuit number, and panel name in the tags for the light fixture. This helps to maximize the use of tag properties and provide complete information about the light fixture in the tags. Take note of any connected load errors that may occur while placing the load on the panel. This helps you update the load of the correct configuration on a panel that cannot accept excess load.

Chapter 11: Electrical Systems
About Electrical Wiring In Revit, you can graphically represent circuit information using wiring. Wiring can be displayed with or without graphical symbols and tick marks. You can also customize the display of these tick marks. Wiring can be automatically generated using the circuit information in a project. You can also manually place the wiring in a view.
Definition Electrical wiring is the physical wiring that connects all electrical components in a building. In Revit, you can display electrical wiring using wire components that contain sizing and circuit information.
Electrical Wire Settings In Revit, you can specify settings to define electrical wiring properties using the Electrical Settings dialog box. To open this dialog box, select Electrical Settings from the MEP Settings drop-down on the Project Settings panel of the Manage tab. In the Electrical Settings dialog box, you can specify settings for ambient temperature, wire crossing gap size, and hot wire, ground wire, and neutral wire tick marks. The Slanted Line Across Tick Marks option enables you to display the tick mark for the ground conductor as a diagonal line across the tick marks for the other conductors. In addition, you can specify whether tick marks should be shown on all wires or only on home runs or should not be shown at all. The following illustration shows the wire settings in the Electrical Settings dialog box.
Wire Tick Marks Wire tick marks are defined under the Wiring category in the Electrical Settings dialog box. You can assign the tick mark style for each type of conductor, such as hot, ground, and neutral. If the wire tick marks are set to be always shown, tick marks appear when wires are created. After wire tick marks are created, you can select them to display control grips for modifying the tick marks. For example, you can increase or decrease the number of hot conductors by clicking the plus or minus control grips of the selected tick marks. If you want to move the location of a tick mark along the wire, use the Moving Tick Marks control grip.
Lesson: Creating Wiring
■
63
The following illustration shows an example of a wire tick mark modification in a project.
Home Runs You can create home runs by manually drawing wires using the Wire tool on the Electrical panel of the Home tab. If you are using the Wire tool and have not selected an electrical component as the endpoint of a wire, Revit creates a home run symbol. After you create symbols, you can select them to display the grips that help move or adjust the arc of a home run. Using the Wire tool, you can also create multiple home runs by wiring electrical components from multiple circuits. The following illustration shows an example of a multiple home run in a project.
Electrical Wire Sizes In Revit, a library of wire sizes is available for the currently selected combination of wire material, temperature rating, and insulation type. Each wire size is assigned ampacity, size, and physical diameter. You can also define whether wire sizing tools should use a given wire size. In the Electrical Settings dialog box, under Wire Sizes, you can specify wire sizing information based on conductor temperature ratings of 60 o C, 75 o C, and 90 o C. Under Correction Factor, you can specify a value for the current-carrying ability of the wire material at specific temperatures. Along with correction factor settings, you can specify ground conductor sizes.

Chapter 11: Electrical Systems
The following illustration shows the Electrical Settings dialog box with aluminum wire sizes available in a project.
Wire Types You define wire types by selecting materials and specifying properties such as temperature rating, insulation, maximum size, and neutral wire settings for a given type of wire. Using different combinations of these properties, you can create standard sets of wire types to be used in Revit. You specify these properties of a wire type under the Wiring Types category in the Electrical Settings dialog box. The following illustration shows the wire types for a project.

Electrical Circuits and Automatic Wire Generation Electrical circuits connect similar electrical components to form an electrical system. When a circuit is selected in a view, you add permanent wiring to the circuit by either selecting the generate wiring controls in the view or using tools on the Modify Electrical Circuits tab. To create permanent wiring, you can highlight a component in the circuit, press TAB to highlight the circuit, and then select the circuit. This automatically generates the wiring. You can then select arced or chamfered wiring to specify the type of wiring for the circuit.
Example The following illustration shows an example of temporary wiring being converted to permanent electrical wiring in a project.

Guidelines for Creating Wiring The following recommended practices help you create wiring effectively.
Guidelines Specify wire settings with available wire sizes to define the wire types that you can use in a Revit model. This allows you to create different wire sizes for the same wire type. Specify wire settings in project template files to save time and maintain consistency across projects. To save even more time, you can specify wire settings in the templates used by your company so that the settings are consistent across projects. Transfer wire settings from one project to another using the Transfer Project Standards tool on the Project Settings panel of the Manage tab. This will expedite the design process and keep company standards consistent across projects. Turn off wire tick marks universally to ensure consistency across all project views by selecting Never for the wiring settings in the Electrical Settings dialog box. You can also turn these settings off in a given view by controlling the settings in the Visibility/Graphic Overrides dialog box in the view. Apply tags to circuits to indicate circuit numbers. When you create circuits, Revit automatically assigns circuit numbers. Applying tags to these circuit numbers helps you save time by removing the numbering system from the process. Manually wire together devices from different circuits. This helps in creating multiple circuit home runs.

Lesson: Monitoring Changes in Linked Files This lesson describes how to monitor changes in files of other disciplines linked to Revit MEP. You begin the lesson by learning about project sharing and the Copy and Monitor tools. Next, you learn the steps to coordinate and monitor changes in the current project. Then, you learn about the Coordination Review tool and some recommended practices for monitoring changes in linked files. The lesson concludes with an exercise on monitoring changes in a linked file of another discipline. In most building projects, you need to collaborate on the building design. For example, a mechanical engineer uses an architect's preliminary building model to devise the initial mechanical design layout of the building. Therefore, proper coordination and monitoring helps ensure that the mechanical model is synchronized with the changes that the architect made to the building model. Effective change monitoring reduces errors and expensive rework during construction.

Chapter 12: Working with Architects and Engineers
About Project Sharing You can share project information across disciplines to create a robust project design. You can link projects and insert elements from one project into another. For example, a mechanical engineer can use an architectural model for creating and analyzing the HVAC design or a structural model for duct coordination.
Definition of Project Sharing Project sharing is the process of linking projects across disciplines. For example, you can share an Autodesk® Revit® Structure model with an MEP engineer. Using Revit MEP, the engineer can create an MEP model on the same design. You can then link the MEP model with the original structural model. Project sharing is effective only when you coordinate and monitor the shared information for updates.
Linking Projects You link a project file using the Import/Link RVT dialog box. While linking, use shared coordinates, origin-to-origin, or center-to-center positioning to specify the location of the linked model in the host project. When you link an Autodesk® Revit® Architecture or Revit Structure project file, its path is saved in the host Revit MEP project file. After linking, if the linked project file changes, you can reload it in the host project file to view the updated linked project file. If the path of the linked project file changes, you can update its path in the host project file using the Manage Links dialog box. You can access the Manage Links dialog box by selecting Manage Links on the Manage Project panel of the Manage tab or on the Link panel of the Insert tab. You can select a linked project file and bind it with the host. Binding converts the linked file to a group in the host file. Then, you can edit the grouped or ungrouped objects. You can also convert a model group into a link, which saves the group as an external file. However, you must exercise caution because if an architectural or structural link is bound to a host Revit MEP file, future updates will not be propagated.
Inserting Elements You can insert 2D elements or drafting views created in a Revit MEP project into a Revit Architecture project by selecting the relevant option from the Insert from File drop-down on the Import panel of the Insert tab. You can also insert Revit Architecture schedules into a Revit MEP project and vice versa. The inserted Revit Architecture or MEP schedules retain the formatting of the original Revit project.
Lesson: Monitoring Changes in Linked Files
■
79
Example of Project Sharing The following illustrations show the different views of host MEP models displaying elements from the linked structural models.
Section view
Plan view
Copy and Monitor Tools You use the Copy and Monitor tools on the Copy/Monitor tab to coordinate and monitor the changes in the building and structural models. To access this tab, activate the Copy/Monitor mode using the Select Link option from the Copy/Monitor drop-down on the Coordinate panel of the Collaborate tab.
Copy/Monitor tools
Copy Tool Using the Copy tool, you can copy elements within a current project or from a linked project to a host project. This establishes a relationship between the copied and original elements, which helps monitor changes to the original element and report differences. After copying elements, you can see the copy/monitor icon displayed next to the copied elements, which indicates that a relationship is established with the original elements and that the copied elements are monitored. If you modify a copied element, a warning message is displayed, indicating that an element has changed. For example, you can copy grid lines from a linked building model to an MEP model using the Copy tool. Later, if you move one of the copied grid lines, a warning message appears.
80
■
Chapter 12: Working with Architects and Engineers
The following illustration shows a warning message box for grid line displacement.
Based on the impact a change has on the MEP model, you can accept or reject the change. You can also accept or reject the change later by performing a coordination review using the Coordination Review tool.
A coordination review lists all the changes made to copied elements.
Monitor Tool You can monitor the elements created in the current project using the Monitor tool. The Monitor tool establishes a relationship between the corresponding elements, for example, between two grid lines. You cannot monitor unlike pairs, such as a grid line and a wall, which are contained in the linked file to the elements that are native to the host file. To do this, you select a pair of similar elements and establish a relationship between them using the Monitor tool. The copy/monitor icon is displayed near the first element you select to indicate that it has a relationship with another element.

81
Coordinating and Monitoring Changes in the Current Project Elements in the current project can be accidentally modified by members of the same team. To avoid inconsistency, monitor the elements so that you get a notification when they are modified.
Procedure: Coordinating and Monitoring Changes in a Current Project The following steps describe how to coordinate and monitor changes in a current project. 1. 2. 3. 4.
82
■
In the view window, draw two instances of an element. Note: Perform this step if the elements to be monitored do not exist in the project. To activate Copy/Monitor mode, click Collaborate tab > Coordinate panel > Copy/Monitor dropdown > Use Current Project. To monitor the relationship between elements in the current project, click Copy/Monitor tab > Tools panel > Monitor. In the view window, select two elements, one after the other, to establish a relationship between them. Notice that the Copy/Monitor icon displays near the first element you select, which indicates that the element has a relationship with the second element. This symbol also indicates that the first element is monitored.
Chapter 12: Working with Architects and Engineers
Coordination Review Tool You use the Coordination Review tool when monitored elements are modified. For example, if a structural project is linked to an MEP project and you are monitoring the level lines in the structural project, Revit MEP notifies you to perform a coordination review when level lines are modified.
Coordination Monitor Warning You can monitor the elements within a Revit MEP model. However, when the elements being monitored are not synchronized, warning messages appear that notify you of any violations. The various violations that lead to the generation of warning messages are as follows: ■ An original monitored element from the linked project has changed. ■ A copied monitored element in the host project has changed. ■ Both the original monitored and copied elements have changed. ■ The original element in the linked file is deleted. ■ The copied element in the host file is deleted.
Coordination monitor warning
Lesson: Monitoring Changes in Linked Files

83
Coordination Review Warning If the monitored elements within a linked file are modified and the file is reloaded, a warning message notifies you that you must perform a coordination review. This occurs either when the linked file is reloaded using the Manage Links dialog box, or when the file is reopened and the modified linked file is reloaded. When the warning message box appears, close the warning and perform a coordination review.
Coordination Review warning
Coordination Review Dialog Box You can access the Coordination Review tool on the Coordinate panel of the Collaborate tab. If you want to check warning messages between elements in the current project, select the Use Current Project option from the Coordination Review drop-down. You can also check warning messages between linked and host projects by selecting the Select Link option from the Coordination Review drop-down. After you select an option, the Coordination Review dialog box opens. It displays an expandable tree of all warnings between monitored elements. You can expand element warning groups until a value under the Action column is displayed.

Chapter 12: Working with Architects and Engineers
Coordination Review dialog box
When you select an element listed in the Coordination Review dialog box, the element is highlighted in the view window.
Action In the Coordination Review dialog box, you can select from a set of options available under the Action column for each warning. The following table describes these options. Option
Description
Do nothing
This option takes no action on the element. This changes the message status so that the warning can be filtered out or considered later.
Reject
This option is used when there is a difference between an element in the host file and its associated monitored element. The difference is because the change made to the element in the host file is incorrect, and a change must be made to the associated monitored element. Note: This command is available only on the In Host Project tab.
Accept difference
This option accepts the change made to the element and updates the relationship. For example, if a pair of grids were 8 inches apart, and one was moved away by 12 inches, the change would be accepted, and the relationship will be set to 12 inches. Note: This command is available only on the In Host Project tab.
Lesson: Monitoring Changes in Linked Files
■
85
Option
Description
Modify, Rename, Move
This option name changes based on the action. If the name of the monitored element has changed, the option is Rename. If a column or a level is moved, the option is Move. If a grid is changed or moved, the option is Modify.
If you select one of these options on the In-a-Linked-Project tab, the element will be changed in the current project, not the linked project.
Comment After you select the appropriate option for each warning, add comments on the action taken. This helps you communicate with other cross-functional team members. For example, as an architect, you can communicate to the structural engineer. Your comments are visible when the link is reloaded.
Guidelines for Monitoring Changes in Linked Files The following recommended practices help you effectively monitor changes in linked files.
Guidelines Use the Copy and Monitor tools in MEP projects to monitor level lines. This ensures that floor-tofloor heights remain coordinated. In addition, it ensures that no elements are placed at incorrect levels that may lead to problems in future analysis, such as calculation of mechanical load, and scheduling, such as electrical scheduling or scheduling to a specific level. Use the Coordination Review tool to perform coordination reviews and generate reports for the changes made to the model. Reviews and reports provide a documented trail for tracking the changes made by team members and the decisions taken for those changes. The reviews and reports also help you ensure that all team members are using the latest version of the design data. Use the Add Comment option in the warning message box to add comments that explain the reasons for changes. These comments become visible to other team members when the link is reloaded. As a result, these changes enhance communication among team members. The comments are also exported to the report for future reference. Select the Use Current Project option of the Coordination Review tool when checking for changes in the monitored elements in the current project. This ensures that a coordination review is done for the entire project. Reload the linked file periodically to check for coordination review warnings instead of keeping it always loaded. You should unload the linked file after performing the coordination review because keeping many links loaded simultaneously affects the software performance.

Lesson: Checking and Fixing Interference Lesson: Conditions This lesson describes how to check and fix interference conditions. You begin the lesson by learning about interference checks. Next, you learn about some recommended practices for checking and fixing interference conditions. The lesson concludes with an exercise on checking and fixing interference conditions. You run an interference check to detect instances where elements in a building model overlap or interfere with each other. These instances are shown in an interference report. You can use this report as a guide to fix the inference conditions. You detect and resolve interference conditions in the design phase to limit cost overruns and the number of design changes required during construction.

Chapter 12: Working with Architects and Engineers
About Interference Checks When you create a building design, you can run an interference check on 3D models to ensure that the elements in the building model are properly placed and do not overlap.
Definition of Interference Checks Interference checks detect overlapping geometry between elements of selected categories. Based on the selection made, the check scans a building model to identify pairs of elements that overlap or interfere with each other. You can perform these checks within a Revit project or between linked projects. Interference checks are performed on a building model database and not on any one view. The check scans all the 3D properties of an element. For example, an interference check recognizes where components of the ducted mechanical systems are in conflict with particular structural elements such as beams or columns. The check generates an interference report that alerts you about the number of interferences caused due to overlapping elements, which may lead to construction errors. For example, an alert occurs when you place a light fixture against an air terminal. On receiving these alerts, you can correct the errors.
Viewing Interference Interferences are not always visible in the existing views. You may need to create new sections or levels that cut through the interfering elements to make the interference visible. For example, in the following illustration, the sprinkler pipes are placed too high and, as a result, they interfere with the ducts. The plan view shows the sprinkler pipe and duct but does not provide any details about the interference. A new section placed through the duct shows the interference.

Guidelines for Checking and Fixing Interference Conditions The following recommended practices help you check and fix interference conditions efficiently.
Guidelines ■

■
Check for interferences frequently and in the early stages of design development. Correcting interference conditions is much easier when the design contains fewer elements. Select a limited set of elements or number of categories to reduce interference check processing time. In large building models, checking all categories against each other can take a lot of time and effort. Create separate 3D views that have been sectioned to certain levels. This helps in coordination by enabling you to view only one floor at a time as opposed to the entire model, where it can be difficult to find a small collision. Refresh an interference report after correcting the existing interference conditions. This helps you check whether the interference has been corrected properly. Refreshing the report checks only for interferences in the current report and does not identify new interference conditions that may be introduced when correcting existing interferences. To correct new interferences, run a new check. Generate and circulate an HTML version of the interference report if you cannot resolve all conflicts without additional input from team members.

Lesson: Creating Callout Views This lesson describes how to create callout views. You begin the lesson by learning about callouts and the steps to create reference callouts. Next, you learn some recommended practices for creating callouts. The lesson concludes with an exercise on creating a callout view of a section. A callout view defines portions of a view as separate views. These separate views are at different scales. Using callout views, you provide an orderly progression of labeled views at increasing levels of detail.

Chapter 13: Detailing and Drafting
About Callouts Callouts act as tools to make coherent document sets. They are designed to enable a user to easily navigate from a detail on one page to a detail on another page in the document. Callout views are used to generate separate views of parts of existing views. You use the callout tag and clip planes to resize callout views. Reference callouts enable you to generate reference callout views that refer to existing views, instead of creating new views.
Definition of Callouts A callout is a view that you place in a plan, section, detail, or elevation view to create a more detailed view of part of a building model from the parent view. The area enclosed within the callout boundary is the callout bubble. A callout bubble is connected to a symbol called the callout head, which shows the detail number and sheet number when the callout is placed on a sheet. A callout bubble and callout head are connected by a leader line. The callout bubble, callout head, and leader are together referred to as a callout tag.
Callout Views When you create a callout, a new view called a callout view is created. A callout view is a separate, large-scaled view of a defined area in a parent view. If the parent view is deleted, the callout view is also deleted. The following table describes the two types of callout views. Callout View Type
Description
Callout in parent view
If you want a callout to share the properties of the parent view, you create the callout view using the same view type as the parent. For example, if you create a callout in a floor plan view using a Floor Plan view type, the callout view is displayed under Floor Plans in the Project Browser.
Callout in detail view
If you create a callout in any plan, section, or elevation view using the Detail View type, the callout view is displayed under Detail Views in the Project Browser. Detail views have the properties of being hidden in the parent view at certain scales and can be made visible in intersecting views.
Lesson: Creating Callout Views
■
101
The following illustrations show the two types of callout views.
Parent view callout view
Detail view callout view
Reference Callouts Reference callouts reference an existing view and do not create a new view. You can place reference callouts in plan, elevation, section, callout, and drafting views. You should consider the following points when creating reference callouts: ■ Reference callouts in section, plan, elevation, or callout views can reference cropped views of the same type as the view in which the reference callout is placed. For example, if you place a callout in Level 2 floor plan and Level 3 floor plan is cropped to show an area that provides the required information, you choose Level 3 floor plan as a reference for the callout. ■ Reference callouts in drafting views can reference any plan, section, elevation, or callout view if the crop region is displayed in these views. There is no parametric relationship between the reference callout and the referenced view, so modifications or resizing performed in a reference callout do not affect the original reference view. For example, resizing the clip planes of a reference callout does not affect the crop region of the original referenced view.
Callout Tags Callout tags are annotation objects that mark the location of callouts. You set the callout head and corner radius parameters for callout tags to define the appearance of the callout tags. Callout tags in both parent and detail callout views appear similar. However, they have distinct properties that determine how and when they are displayed.
Clip Planes The boundaries of a callout bubble define clip planes for the extents of the callout view. You can resize the callout view by selecting the callout bubble and dragging the clip planes, which are represented by control dots. Resizing the crop region of a callout view resizes the callout bubble in the parent view.

Open the view in which you want to create a callout to an existing drafting view. Click View tab > Create panel > Callout. On the Options Bar, select the Reference Other View check box. Select the view name that you want to reference from the Reference Other View list. You need to create a new drafting view if there are no existing views to reference. Note: If a view in the Reference Other View list is on a drawing sheet, the detail number and sheet number are displayed next to the view name. To place one corner of a callout, click the area of the view where you want to place the callout. Drag the cursor and click again to create a callout bubble.
Double-click the callout head to set the referenced view as the active view. Note: The reference callout head includes a label. To change the label text, you edit the Reference Label type parameter of the callout family.

Plan the use of views and callouts to provide a logical sequence that directs users to move from views providing little detail to views providing greater levels of detail. Place callouts on the same sheet as the parent view or place details on sheets by category, such as panel elevations or duct details. In both cases, the sequence should direct the user through the sheet set easily, preferably in one direction. This makes the documents easy to read and enables you to avoid requests for additional information about the created document sets. It also decreases the time required to gather information about the construction documentation set. Use standard details in drafting views as references in document sets for multiple callouts that detail the same condition. This saves time and enables you to leverage previously drafted document sets. Set the callout head and corner radius parameters for callout tags by selecting the Callout Tags option from the Settings drop-down on the Project Settings panel of the Manage tab. If an organization uses round callouts, set the radius to a large value. This enables you to quickly standardize the appearance of callouts.
Example The following example shows a round callout used in a drawing.

Chapter 13: Detailing and Drafting
About Detail Views You create detail views to provide information on how a building should be constructed. A detail view represents a building model with finer details in terms of construction and fabrication than largescale views. Using the detail view, you can add more information to your building model in the form of annotations and 2D lines on specific parts of the model.
Definition of Detail Views A detail view is a view of all or a specific portion of a plan, elevation, or section view. This view provides a greater level of detail at a different scale from its parent view. You can create detail views and access them from Detail Views in the Project Browser. You can create a detail view quickly by using the Callout tool. You can also duplicate a view, crop it, and change the scale to make a detail view. Detail view types are available for sections and callouts in the default templates. The following illustration shows a callout of a plan view listed as a detail view in the Project Browser.
Detail Levels You can view a building model in three levels of detail: coarse, medium, and fine. These detail levels are available on the View Control Bar.
Lesson: Working with Detail Views
■
109
Changing the detail level affects the display of the elements in a building model. For example, in the illustration on the left, the pipes are at the coarse detail level and appear as single line pipes. In the illustration on the right, the pipes are at the fine detail level and appear as double line pipes.
Coarse detail level
Fine detail level
Detail Level Option To set the detail level based on the view scale for new views that you create, you use the View Scaleto-Detail Level Correspondence dialog box. You can access this dialog box by selecting Detail Level from the Settings drop-down on the Project Settings panel of the Manage tab. Additionally, depending on a view, you can override the detail level by setting the Detail Level parameter in the View Properties dialog box.
Detailing Tools You can use the detail view of part of a building model as background to specify additional information. This process of adding more information is known as detailing. For example, consider a section of a building model where the pipe vent penetrates the roof. In this section, you can add information such as text notes, dimensions, and symbols. You use 2D detailing tools for detailing. These tools are available on the Annotate and View tabs. The following table describes the detailing tools.
110
Tool
Description
Callouts
Creates a callout to display a close-up view of a plan, section, or elevation view. Details are added to the callout view.
Detail Lines
Places 2D lines in the detail view. These lines can trace over model components or add lines that are not shown in the model.
Dimensions
Applies specific dimensions to the detail for specifying exact distances or placement instructions.
Text Notes
Specifies construction methods and materials.
Detail Components
Creates and loads custom detail components to place the details. Detail components may be actual construction components, such as floor drains, p-traps, and roof drains.
■
Chapter 13: Detailing and Drafting
Tool
Description
Symbols
Places a symbol such as a direction arrow or a break mark to indicate omitted information.
Masking Region
Creates masking regions to obscure elements in a view.
Filled Regions
Creates detail regions and gives them a fill pattern to represent surfaces such as concrete or compacted earth.
Insulation
Places a detail component to represent insulation. You do this in a section detail that shows the structure of a roof or wall.
Detail Groups
Places pre-existing groups or combines detail elements into groups that you can reuse within a project or in other projects.
You use detailing tools, such as Detail Lines, Detail Components, and Filled Regions, more frequently than other tools.
Detail Lines The Detail Lines tool used for creating 2D detail lines has the same drawing options as the Lines tool. You use the Lines tool when creating ducts, pipes, or wires. Detail lines are specific to a view and are used in drafting views, which have no reference to the building model.
Detail Components You use the Detail Component tool to place 2D detail components, such as fasteners and connections, in a detail view. Detail components are similar to annotation elements and are visible only in the view in which you place them. You can use these detail components and create custom detail components when you fill details for construction documents. You load detail components into a file from the Detail Component libraries that are installed with Revit®. These detail components are stored in the library according to the CSI MasterFormat. The following illustrations show 2D detail component families.
2D family of a sink section
2D family of a floor drain section

111
Filled Regions Filled regions are detail elements that consist of repeated line patterns within a border. You place a filled region by sketching its border and specifying a pattern. Filled regions can be opaque or transparent. Opaque regions hide the surface on which they are placed. White and opaque filled regions are known as masking regions. You can set the edge lines of the filled and masking regions to the invisible linetype, which hides the edge lines.
Hidden Line The graphics display mode that Revit most commonly uses is known as Hidden Line. This mode shows only surfaces and edges, and objects behind other objects are hidden. You can show the edges of hidden objects in a detail view. To do this, you either add detail lines or override the display of edges by using the Linework tool on the Edit Linework panel of the Modify tab. Standard drafting convention in plans and sections includes linework that indicates when a line representing an object edge is hidden. At times, when you want to indicate that an item is not really visible, you use the dashed linetype known as Hidden. Revit also provides a linetype named Hidden Line that is green and has a slightly different pattern. The following illustrations show a hidden line view and the hidden linetype.
Hidden line view of a model
Detail lines using the hidden linetype in a detail view of a model
Draw Order of Elements The draw order of elements in a detail or drafting view determines which 2D elements, such as filled regions, hide other elements. You can set the draw order for detail items in a detail view. By default, elements that are added later hide those placed earlier.
Detail Groups You can assemble detail objects, such as detail lines, filled regions, and text to create detail groups. You can group model and detail elements and combinations of both. Creating detail groups minimizes repetition of elements. You can place detail groups in many views, save them as library files, and access them from the Project Browser.
112
■
Chapter 13: Detailing and Drafting
Draw Order of Detail Groups The draw order of a detail group is the sequence in which you group the detail elements. The draw order of a detail group does not change when the group is moved, copied, or inserted. You can change the draw order of individual group members. To do this, you need to edit the group. After you edit the draw order of the members of a detail group, all instances of that detail group are updated with the new draw order.
Sorting Detail Element Display Depth You sort the display depth of selected detail elements in a view using Bring to Front and Send to Back on the Arrange panel of the Modify Detail Items contextual tab. These options are available when you place or select detail elements in the view. The following table describes the display depth sorting options. Option
Description
Bring to Front
Places a detail element in front of all detail elements in the view.
Send to Back
Places a detail element behind all detail elements in the view.
Bring Forward
Moves a detail element incrementally closer to the front of all detail elements in the view.
Send Backward
Moves a detail element incrementally closer to the back of all other detail elements in the view.
Example of Detail Views The following illustrations show examples of detail views.

Creating Detail Views You can create a new detail view or change the type of an existing section or callout view. When you create a detail view from an existing view, you can resize the crop region and rename it.
Procedure: Creating a Detail View from an Existing View The following steps describe the procedure to create a detail view from an existing view. 1. 2. 3.
Open a view that contains a section or callout that you wish to detail. Open the Instance Properties dialog box. In the Instance Properties dialog box: ■ Select Detail from the Type list. ■ Under Graphics, select a view scale from the View Scale list. In the view window, resize the crop region, if required. In the Project Browser, rename the new detail view.
4. 5.
You can change any section view that has not been created with a Detail View type to a detail view by selecting the section symbol in the parent view and selecting a Detail View type from the Type Selector drop-down. The view will then move to the appropriate Detail View category in the Project Browser. You can also change the view type of callouts placed in section views. However, you cannot change the view type of callouts placed in plan views.
Procedure: Creating a New Detail View The following steps describe the procedure to create a new detail view. 1. 2.

Select a view. Select a view in the Project Browser that you want to save to a separate file. Select Save to New File from the shortcut menu. Save the view. Save the view as an RVT file in a selected library folder. Insert the view. Insert the view in another project, as required. You can insert schedules, drafting views, reports, sheets, or 2D content from one project to another using Insert from File on the Import panel of the Insert tab. Open the view. Open the inserted view to reuse it. You need to ensure that when you open a view for reuse, its properties are also transferred to the project. You can also select a view scale for the view that you want to reuse.

115
Guidelines for Saving and Reusing Detail Views You should identify the views, if any, that you can save in a project to reuse later. The following recommended practices help you save and reuse detail views.
Guidelines ■
■
■
■
116
When you export a sheet, the placement of views on the sheet is maintained. This enables you to create and reuse standard detail sheets. When you import a sheet, the titleblock on the sheet is updated with project information and the sheet name is incremented according to your sheet naming convention. To import 2D elements from a saved model detail view, you must activate a drafting view. This results in a successful import of the 2D elements. However, model elements are not imported. When you import a drafting view, a new drafting view is automatically created to retain the imported view. This enables you to quickly create detail sheets that reuse standard details but vary in layout. You can use detailing in Revit to make good use of predrawn detail components. After you create details, particularly standard details that do not reference a specific model, save them to build a library of detail components in the Revit format. This helps you to insert details quickly in future projects and avoids having to recreate detail blocks.

Lesson: Working with Drafting Views This lesson describes how to work with drafting views. You begin the lesson by learning about drafting views. Next, you learn the process and some recommended practices of reusing these views. The lesson concludes with exercises on creating drafting views and importing a view and a CAD file. When you create and document a building model, you may want to create a detail that is not associated with the building model. Instead of creating a callout and then detailing it, you can use drafting views to create these details. You can also save drafting views and reuse them across projects.

About Drafting Views You create drafting views when a project contains drafted details. During design, if you change a building model, the drafted details do not change; therefore, the details require no adjustment. However, in model views, you may need to adjust the 2D detail components if the model changes.
Definition of Drafting Views Drafting views provide a 2D detail drawing of a specific part of a building model. In a drafting view, you can use 2D detailing tools such as detail lines, detail regions, detail components, insulation, reference planes, dimensions, symbols, and text. Drafting views are drawn and not modeled. For example, a drafting view of a typical diffuser connection does not include the diffuser and duct elements, but shows only the lines that represent the diffuser and the duct. In drafting views, you include only the elements that you either create using 2D detailing tools or import from the standard CAD detail library. You can create drafting views at different view scales and detail levels. You can also save drafting views and reuse them across projects. You place a drafting view on a drawing sheet by dragging the view to the sheet, which is similar to placing a floor plan. Drafting views are saved with the project and are listed under Drafting Views in the Project Browser.
Example of Drafting Views The following illustration shows detail components with dimensions and text notes in a drafting view.

Chapter 13: Detailing and Drafting
Process of Reusing Drafting Views You can save the drafting views that you create as separate files in the detail drawing library. You can then reuse these drafting views in other building models.
Process: Reusing Drafting Views The following illustration shows the process of reusing drafting views.
The following steps describe the process of reusing drafting views. 1.
2.
3. 4.
Create drafting views. You create a drafting view using the Drafting View tool on the Create panel of the View tab. You can create different types of drafting views based on the type of application that you want to display in a specific drafting view, depending on disciplines such as HVAC or electrical. This organizes the different views in the Project Browser. Annotate in drafting views. You annotate drafting views by using various detailing tools on the Detail panel of the Annotate tab. These tools include Detail Line, Region, Component, Revision Cloud, Symbol, Detail Group, and Insulation. Save drafting views. You can save drafting views as external files by using the Save to New File option on the shortcut menu of the drafting view. Import drafting views. You can reuse an existing drafting view by importing it into the current project using the Insert From File option on the Import panel of the Insert tab.

Guidelines for Reusing Drafting Views Following these recommended practices, you can reuse drafting views effectively.
Guidelines ■
■
■
■
126
Save drafting views to external files so that members of other teams can reuse them. This practice helps you build a detail library. Save drafting views to the existing file system with relevant file names, which can be easily identified, so that the files are visible to other team members. This makes the commonly used files available to other team members, facilitating better work coordination. Ensure that you post revised versions of views if any details change in the drafting views so that the latest design information is available. This practice increases the efficiency of the design process and reduces errors. Export views to CAD formats so that detailers, who are proficient in CAD programs, can also contribute in a Revit project. After the detailers have worked on the CAD files, you can import them as drafting views. This enables detailers who are proficient in programs other than Revit to participate in a Revit project.

Lesson: Working with Text and Tags This lesson describes how to work with text and tags. You begin the lesson by learning about text and tags. Next, you learn some recommended practices for working with them. The lesson concludes with an exercise on working with text and tags. Annotations, such as text and tags, are an important part of construction documents. Annotations provide specific instructions that are necessary for fabricators and constructors to understand a building design. You use text to provide descriptive information about building elements. Tags are used to label building elements. The following illustration shows a plan view with tags and a text note.

Chapter 14: Annotations and Schedules
About Text A building design goes through various stages before being implemented. At each stage, different people are involved who may want to add explanations and instructions to the design using text annotations. You can add text to views or sheets in your project to make the building design easy to understand for the people next in the cycle.
Definition of Text Text is the information added to a view to label or provide descriptions about the building elements. It is a view-specific component and therefore automatically changes in size along with the view scale. You can use the default text types or create custom text types based on font or size, as required. Text can have leaders that point to specific elements, areas, or conditions in a view. You add text to a view as a text note using the Text tool. When you add text, the text and the leaders automatically snap into alignment with the other text and leaders in the view. After adding text, you can format it for various parameters, such as size, font, justification, width, underlining, lineweight, background, and color. To keep the building elements in a view clear and readable, you can move text to different positions. You can also edit and wrap text. In addition, you can copy or paste text from other applications, such as Microsoft Word. You can also add or remove leaders of a text note at any time, if required.
Model Text For special instances, such as putting a representation of signage on a building, you can add model text. Model text is a model component and is therefore visible in all the relevant model views. It does not change when the view scale is changed.
Example of Text The following illustration shows a drafting view with text notes.
Lesson: Working with Text and Tags
■
139
About Tags You use tags to label building elements. Tags use unique symbols to represent each building element. Unlike text, the values displayed in tags are automatically updated when a building design is updated.
Definition of Tags Tags are annotations that display parametric information about the elements with which they are associated. Tags are view-specific and therefore scale with the view. When you place tags, they automatically align with the other tags in the view. Revit provides predefined tag families for all building elements. Some tags such as air terminal and duct are preloaded into the default project templates. The preloaded tags are automatically placed in a view when you add a corresponding building element. For building elements that do not have corresponding preloaded tags, you need to load the tags from the software library. You can create custom tags by editing the predefined tag family files according to the required graphic standards. Tags can be added with or without leaders and can be oriented horizontally or vertically. You can modify tags by changing their position in a view, turning their leaders on or off, and changing their orientation.
You can tag a building element with more than one tag if multiple tag types are loaded for that element.
Types of Predefined Tags The following table describes the various types of predefined tags.
140
Type
Description
Air terminal
Displays the Type Mark property of air terminals and the specified amount of CFM. Air terminals are numbered and scheduled by type, not individually.
Light fixture
Displays the Type Mark property of light fixtures. Light fixtures are numbered and scheduled by type, not individually.
Space
Displays the name and number of spaces by default.
Duct
Displays the size property of ducts. Ducts are sized by diameter or by width and height.

Chapter 14: Annotations and Schedules
Tag Tool Options You can add tags in a view using the tools available on the Tag panel of the Annotate tab. The Tag panel provides five tools: Tag by Category, Tag All, Multi-Category, Material, and View Reference.
Tag tools on the Tag panel of the Annotate tab
The following table describes the various tag tools available on the Tag panel. Option
Description
Tag by Category
Identifies building elements, such as air terminals, piping, and plumbing fixtures, in a drawing. When you tag building elements by category, Revit recognizes the element type and provides an appropriate tag type.
Tag All
Places tags by category on all or selected building elements in a view.
Multi-Category
Identifies building elements across element categories based on the predefined filters.
Material
Identifies materials, such as studs and drywall in walls, as specified in a building design.
View Reference
Indicates the sheet number and detail number of a view that has been split with a Matchline. This tool is active only in views with dependency relationships.
Example of Tags The following illustrations show the various types of predefined tags.

■
■
142
Place text and tags after a view is created and made ready for annotation if you anticipate changes to the view scale. Following this practice helps you save the time spent in coordinating the views for printing. Create copies of the main model views and name them appropriately so that you can quickly add text and tags to create specific views. For example, a floor plan view can be duplicated with detailing repeatedly to set up the mechanical, electrical, piping, and plumbing plans. Each duplicate plan view can contain the required text and tags. If you work on similar building designs, you can save these plan views in a project template to reduce the setup time and speed up the documentation phase. Plan and crop the documentation views to make placing text notes easier and more efficient. Ensure that text notes and their associated leaders do not obscure the graphic display of building elements. Also check that notes are aligned. These measures will enable users to read text notes easily. Create different types of text by adding leaders with different end symbols, such as dots and large arrows. You can then use different text symbols for specific situations or conditions. Load more than one tag type for building elements when you want to tag an element for different purposes across views. Following this practice provides flexibility to views and improves the quality of documents. Use the spelling checker available on the Text panel of the Annotate tab to ensure correct spellings are used in text and tags.

Lesson: Working with Dimensions This lesson describes how to work with dimensions in a building model. You begin the lesson by learning about temporary and permanent dimensions. Next, you learn about some recommended practices for working with dimensions. The lesson concludes with an exercise on working with dimensions in a building model. You place dimensions to set and modify the distance between elements in a building model. You use temporary dimensions to quickly and accurately populate a design and permanent dimensions to annotate the design. The following illustration shows a dimension associated with a duct element.

About Temporary Dimensions Dimensions are system families that have type and instance properties. You can customize these properties to create new dimension types that better suit your requirements. For example, you can change the tick mark, line weight, and color of dimensions. In addition, you can control the witness lines for dimensions. You can also set the font, height, and unit format for dimension text. Dimensions can be of two types, temporary and permanent. Temporary dimensions are automatically displayed when you select an element in a building model. They enable you to place and move elements accurately in a building model.
Definition of Temporary Dimensions Temporary dimensions are the dimensions displayed in reference to the nearest element that is perpendicular or parallel to the element that you are creating or have selected. The following illustrations show the temporary dimensions of various elements.
Temporary dimensions for a duct being created
Temporary dimensions for a selected element
Temporary dimensions disappear when you add another element to the building design, reducing dimension clutter. To edit a temporary dimension, you need to select the element and change the dimension value.

Listening Dimensions Temporary dimensions that appear when you create elements are called listening dimensions. Listening dimensions appear in bold and change as you create an element, such as a duct. You use listening dimensions to adjust the length or placement of elements. The following illustration shows the listening dimension that displays while you are drawing a duct. Notice that the listening dimension is displayed from the start to the endpoint of the duct.
You can modify the listening dimension while creating or after placing an element in a drawing by typing the required dimension directly.

■
Chapter 14: Annotations and Schedules
The following illustrations show the listening dimension of a duct modified by typing the new dimension.

When you enter dimension values using imperial units, you can enter either the feet and inch symbols, such as 10' 6 3/4", or just the feet and inch numbers separated by a space, such as 10 6 3/4. If you enter a value without specifying a unit, such as 10, it is interpreted as 10 feet (10').
Creating Elements with Temporary Dimensions While creating elements with temporary dimensions, you can specify temporary dimension settings and dimension increment values.
Specifying Temporary Dimension Settings You can specify settings such as snapping points for temporary dimensions. For example, you can specify that temporary dimensions snap to the centerlines or to the faces of a wall. To specify such preferences, you use the Temporary Dimension Properties dialog box, which can be accessed from the Settings drop-down on the Project Settings panel of the Manage tab. You can set separate preferences for walls, ducts, and pipes.
Dimension Increments When you create an element, its temporary dimension value is incremented based on the amount you zoom in the view. The increment also depends on the dimension snap increment settings specified in the Snaps dialog box, which is also accessible from the Settings drop-down. You can set increment values for length and angular dimensions separately using the Snaps dialog box.
Lesson: Working with Dimensions

151
Viewing Temporary Dimensions You view the temporary dimensions of an element by using the Modify option on the Quick Access toolbar or on contextual tabs that appear during specific operations. When you click Modify, other commands end and you can select the desired element. The temporary dimensions for an element might differ from those that were originally displayed while creating the element. This is because when you create an element, its temporary dimensions are displayed in reference to the nearest element, which might have changed.
Modifying Temporary Dimensions You can resize or move elements by modifying their temporary dimensions. You can move the witness lines of temporary dimensions to reference specific elements. To do this, you use the blue square control on the witness line. Selecting the square enables you to cycle its position, such as from wall centerline to alternate faces. The changes made to the witness lines are not saved. The following illustrations show a duct being repositioned by having its temporary dimensions modified.

After modifying the temporary dimensions
Example of Temporary Dimensions The following illustration shows the temporary dimensions of a selected pipe. The temporary dimensions indicate the length of the pipe, the end offset from the finished floor, and its position relative to the other walls in the drawing.
About Permanent Dimensions You use permanent dimensions if you want to continuously display the dimensions of the elements in a building model view. Dimensions adjust to the scale of the view. You do not need to create dimension styles for standard view scales. There are two methods by which you can associate permanent dimensions with an element. You can make temporary dimensions permanent by using the dimension symbol, or you can add permanent dimensions using the Dimension tools on the Dimension panel of the Annotate tab.
Definition of Permanent Dimensions Permanent dimensions are the dimensions that you add to elements after placing them in a building model. Unlike temporary dimensions, permanent dimensions are visible even if the elements are not selected. Permanent dimensions occur in two states, modifiable and nonmodifiable. Permanent dimensions for an element can be modified individually only when the element is selected. In the nonmodifiable state, you cannot edit the values of permanent dimensions because the element with which they are associated is not selected. You can select dimensions and change their properties, lock or unlock them, and apply equality constraints.

Specifying Wall Dimension Preferences You can specify the way the pointer snaps when you assign permanent dimensions to a wall. For example, you can specify the reference line that should be highlighted first. You can also specify the place where the pointer snaps first when you move it over a wall. You can make these specifications by selecting appropriate options from the Place Dimensions list on the Options Bar. The following illustration shows the Place Dimensions list on the Options Bar.
The Place Dimensions list is activated for all dimension types, except the linear dimension.
Wall Centerlines Using this option, you can make a wall measurable from the centerline.

Locking Permanent Dimensions When you add a permanent dimension to an element, an unlocked padlock appears near the dimension line. The padlock indicates that you can modify the length of a wall and the distance between walls. For example, you can drag the wall ends on either side to increase the wall length. You can also drag the wall upward or downward to adjust the distance between two walls. After making the required modifications, to prevent the dimensions of a wall from changing, you can lock the permanent dimensions by using the padlock. If required, you can unlock dimensions that you have locked. The following illustrations show locked and unlocked permanent dimensions for a wall.

Editing Witness Lines You can add witness lines to a permanent dimension using the Edit Witness Lines tool. This tool is available on the Witness Lines panel of the Modify Dimensions contextual tab that appears when you select a dimension. You can also right-click a dimension and select Edit Witness Lines from the shortcut menu. You click additional objects to include them in the dimension string. The resulting dimension string is a single object. You can remove witness lines from a dimension string by selecting the permanent dimension and right-clicking the blue square control in the middle of the witness line. Then, select Delete Witness Line from the shortcut menu.

Guidelines for Working with Dimensions The following recommended practices help you work efficiently with dimensions.
Guidelines ■
■ ■
■
■
■
162
Change temporary dimensions to permanent when you need to refer to the distance between various elements frequently while working. Using permanent dimensions is quicker than selecting the same element repeatedly to find out its distance from other elements. You can delete permanent dimensions at any time if they clutter a view and re-create them later. Click the EQ symbol when creating a dimension string to quickly make objects equidistant. Add parallel reference planes or model lines in the corners of a room when you want to quickly place dimensions across the corners. This is recommended because Revit does not easily add dimensions to nonparallel objects. After adding parallel reference planes, you can place the dimensions between these planes and then hide the planes. You can add dimensions to certain wall endpoints and corners by using select+TAB. Note: Alternatively, you can use the Tape Measure tool to determine the distance between corners. Add dimension styles to project templates to avoid having to create dimension styles for each project. Use the Duplicate View option to create a copy of a view that does not display the dimensions and notes you placed while working on a building model. This helps you show a neat view to the client without losing the details. Note: You can hide individual dimensions as well. Adjust view scale before placing dimensions and text. Dimensions and text automatically adjust size to the view scale of the view they are placed in. If you change the scale of a view after placing dimensions and notes, you may need to check the placement of dimension text and notes to maintain clarity.

Lesson: Creating Legends This lesson describes how to create legends with notes, annotation symbols, and model elements. You begin the lesson by learning about legends. Next, you learn some recommended practices for creating legends. The lesson concludes with an exercise on creating a legend with annotation symbols, notes, and model elements. Construction documents consist of drawings and specifications that define the intent of a project design. You use legends in construction documents to display lists of various building components and annotations used in a project. This helps team members and clients to interpret drawings correctly. Standard information such as explanations of symbols or generic notes is typically the same for different projects and is repeated on multiple drawing sheets. To avoid the errors that can occur when duplicating information on multiple sheets, you create legends and place them on the required sheets.

Chapter 14: Annotations and Schedules
About Legends When documenting a design or project, you can create legends to explain the symbols, materials, and elements used in a project instead of adding notes repeatedly to views.
Definition of Legends A legend is a view containing two-dimensional annotation elements, including text, dimensions, symbols, tags, filled regions, and detail lines. Typically, legends appear as tables that contain one column for graphic symbols and another for explanatory text to define the symbols used in a particular view or for the entire project. You can use the same legend on multiple drawing sheets. In addition, you can add different components to a legend using standard Revit tools.
Legend Components Legend components are two-dimensional representations of model elements in the plan or section view that you can add to a legend view. Some examples of legend components are types of columns, beams, floors, and walls. You can add these components to a legend by using the Legend Component tool available in the Component drop-down on the Detail panel of the Annotate tab. Legend components are available only for the model elements currently loaded into the project. Legend components have detail level properties that you can control independent of the detail level of the legend. In addition, you can use the legend visibility settings to control the display of the subcategories of the component families in a legend.
Tools for Creating Legends You use annotation tools to add information to the legend components in a legend view. Text and Dimension are two commonly used annotation tools. Using the Text tool, you can specify the name or any other information for a legend component. Using the Dimension tool, you can add dimensions to a legend component to specify its size and the distance between two points within the component. You can also add lines and filled regions to legend components.

Annotation Symbol Legends Annotation symbols in a legend represent sheet annotations, such as section heads and elevation symbols. To place annotation symbols in a legend, you use the Symbol tool on the Detail panel of the Annotate tab. After adding the annotation symbols, you add text to the legend to describe them.

Model Element Legends Model element legends are symbolic representations of model elements with some descriptive text. You create a model element legend by creating a legend view and then adding model elements using the Legend Component tool available in the Component drop-down on the Detail panel of the Annotate tab.
Model elements and notes added to a legend
You can use legend views to create typical details that are parametrically linked to a model view. When the type parameters for a model element change, the model element in the legend view also changes.

Set up legends based on the standard documentation of your organization and load them in the project templates. Then, you can place legends on the required sheets from the templates. This practice saves time when you are creating construction documents of a project. Import CAD files with legends to reuse the previously developed legend content. This helps you avoid rework and errors, and allows you to use the same legend content in different project files. Copy and paste legend information from one project file to another because you cannot save legend views as separate files. This helps you save time and increase efficiency when duplicating information across multiple project files.

Lesson: Working with Schedules This lesson describes how to work with schedules. You begin the lesson by learning about the types, characteristics, and properties of schedules. Next, you learn steps to export schedules and modify the fields in a schedule. Then, you learn some recommended practices for working with schedules. The lesson concludes with an exercise on creating and modifying a lighting fixture schedule. Schedules provide information about building elements in a project, such as lights and mechanical equipment, which can be exported to other applications for cost lists, estimates, and other quantity tallies. You use schedules to display the properties of selected building elements in a tabular format. In Revit, the schedules update automatically and therefore eliminate the errors that can occur in a manually compiled list.

About Schedules You can view a building model in different ways. One way is to create a schedule that displays information about elements in a tabular format. A schedule updates automatically as the building model develops. You can format, view, and export schedules. You can also place them on drawing sheets to be used in documentation sets.
Definition of Schedules A schedule is a formatted view of a building model based on the criteria you provide. It is a tabular display of information extracted from the properties of elements in a building model. Each property of an element is represented as a field in the schedule. Schedules can list every instance of a particular type of element in different rows or condense information about multiple instances of an element into a single row.
Types of Schedules You can create three types of schedules using the Schedule/Quantities tool from the Schedules dropdown on the Create panel of the View tab. The three types of schedules are component schedules, multi-category schedules, and key schedules. You can also create specialized schedules, such as material takeoffs, view lists, drawing lists, note blocks, and revision schedules, from the Schedules drop-down. The following table describes the various types of Schedule/Quantities.
182
Schedule/Quantities Type
Description
Component
Lists the selected component properties in a tabular format. For example, you can create a lighting fixture schedule that lists the properties of lighting fixtures, such as type, wattage, lamps, and count. Component schedules can be instance or type schedules. Instance schedules list each component as a separate line item, whereas type schedules group components of the same type into a single line item.
Multi-category
Lists the components that hold shared parameters. Shared parameters span more than one project. The available fields for this type of schedule include the shared parameters.
■
Chapter 14: Annotations and Schedules
Schedule/Quantities Type
Description
Key
Lists the keys that you define for elements that consist of multiple items with the same characteristics. The keys act as a grouping mechanism, like style definitions. Key schedules are automatically populated with information about the element properties in the schedule fields. For example, an air terminal schedule might have 100 diffusers with the same width and depth. Instead of manually entering the information for each of the 100 diffusers in the schedule, you can define keys that fill in the information. You define key schedules according to project specifications. When you define a key, it becomes part of the instance properties of the scheduled element. If you display the properties of that element, you see the new key name. When you apply a value to the key, the attributes of the key are applied to the element.
Material Takeoffs A material takeoff is a specific type of component schedule. It lists the subcomponents or materials of any Revit family. Material takeoffs have all the functionality and characteristics of other schedules. They help you display details of the assembly of a component. Any material that is used in an element within Revit can be scheduled.
View Lists A view list is a schedule of all views that show view parameters. You use view parameters for grouping and filtering the Project Browser organization. You can view and modify various view parameters for multiple views at a time.
Drawing Lists A drawing list is a schedule of all drawing sheets in a project. It functions as a table of contents for the project and is typically placed on the first sheet of a documentation set.
Keynote Legends A keynote parameter is available for all model elements, detail components, and materials. Keynote legends group common types of keynotes and can be placed on multiple sheet views. You create keynote legends using the Legends drop-down on the Create panel of the View tab.
Note Blocks Note blocks are schedules that list the instances of annotations that you apply using the Symbol tool on the Detail panel of the Annotate tab. Note blocks are useful for listing notes that are applied to elements in a project. For example, you can provide building descriptions for walls by attaching a note to each wall.
Revision Schedules Revision schedules are included with most Revit titleblocks. After you create a drawing sheet with a default titleblock, you can begin recording revision information on that sheet. You can add a revision schedule to a custom titleblock.

Embedded Schedules In Revit, after you create a schedule for rooms and the electrical, air, piping, plumbing, or fire protection system, you can create an embedded schedule to show information about the components that are members of these systems.
Schedule Management After you create a schedule, you can perform various operations on it, such as viewing and updating the schedule. When you create a schedule, it is added to the Project Browser listing. You can display the schedule in the view window by double-clicking the schedule name. You can also add the schedule to a drawing sheet by dragging the schedule to the drawing sheet in the view window. A schedule is a view of the model that updates automatically when you make changes to those parts of the project that affect it. For example, if you move a wall, the floor area of the room in the room schedule updates accordingly. Schedules are associated with an entire project, including the building model. Therefore, when you change the properties of building components in a project, the associated schedule is also updated. For example, you can select a lighting fixture in a project and change its manufacturer property. As a result, the lighting fixture schedule also updates. You can also edit a property of a building model by selecting the field corresponding to the property in the schedule and entering a new value for the property. Consequently, the schedule and the element type change.
Example of Schedules The following illustration shows a lighting fixture schedule.
About Schedule Properties Schedules contain a list of fields that display element properties, such as the areas of rooms or the levels of plumbing fixtures. The properties of a schedule include the fields to be included, the sequence of the fields, and the way the fields are presented. You define the properties of schedules by using the tabs in the Schedule Properties dialog box. Based on project requirements, you can add, filter, sort, format, and change the appearance of the fields for properties in a schedule.
Definition of Schedule Properties Schedule properties define the structure and presentation of a schedule. These properties help you modify the information types that you want to include in a schedule and the appearance of that information.

Note: You can specify the calculation criteria in the Calculated Value dialog box.
Guidelines for Working with Schedules The following recommended practices help you effectively work with schedules.
Guidelines ■
■
■
Create schedules that display only important or critical fields so that the schedules are easy to understand. Use the Hidden Field check box on the Formatting tab in the Schedule Properties dialog box to hide the fields that you want to retain but not show in the schedule view. Use headers, footers, and blank lines to identify and separate groups of similar information in a schedule to improve readability. You can create these headers, footers, and blank lines using the Sorting/Grouping tab in the Schedule Properties dialog box. Click Show repeatedly in the Show Elements in View dialog box to open all the model views that display the element selected in the schedule table. This helps you easily check and modify the selected element in all views.

Chapter 15: Construction Documentation
About Titleblocks A titleblock defines a printed page. It holds space for view information that helps you to identify a building model for construction purposes. It also provides technical information about a project, such as the name and location of the project and the sheet issue date.
Definition of Titleblocks Titleblocks are templates for sheets. You can load standard titleblocks into a project or create custom titleblocks using the Family Editor and save them on a network. When you load a titleblock, Revit searches for the titleblocks in the Titleblocks folder in the default Imperial and Metric libraries. However, you can change this location based on your requirements. You can create custom titleblocks by specifying the required sheet size and then adding borders, company logo, and other information on the sheet. After loading or creating a titleblock, you can import JPEG or BMP images in a titleblock. You can also import existing drawing formats from other software packages by exporting a titleblock page in the DXF™ or DWG™ format and then importing the titleblock page to a Revit titleblock file. You can save the titleblock as a family file with a Revit .rfa extension.
Elements of Titleblocks You can create different elements of a titleblock, such as family types, dimensions, lines, and masking regions, by using various tools available in the Family Editor. Titleblock elements contain all the information that needs to be placed in a sheet. The following illustration shows the Create tab in the Family Editor.
The following table describes some basic tools on the Create tab in the Family Editor. Tool
Icon
Description
Family Types
Allows you to specify and manage predefined properties within a family using the Family Types dialog box. The most common use of titleblock family types is for creating titleblocks of different sizes.
Dimension
Shows and controls distances between borders or lines placed in a titleblock.

Tool
196
Icon
Description
Line
Draws borders around titleblocks. You also use the Line tool to draw lines and shapes to divide the drawing sheet into two areas, one that holds views and another that holds project and company information.
Reference Line
Creates a parametric family skeleton. The elements of a titleblock can align with or attach to reference lines. Reference lines are invisible when a titleblock is loaded into a project and do not highlight when a titleblock instance is selected.
Masking Region
Applies a white-filled region as a mask to hide a region of a family.
Filled Region
Creates a view-specific, 2D graphic. Filled regions are areas that are parallel to the sketch plane of a view and contain a pattern that can be edited.
Symbol
Places 2D annotation drawing symbols, such as a North arrow, into a titleblock.
Text
Adds text to a titleblock. You need to use the Family Editor to add or modify titleblock text. You cannot modify the text in a titleblock directly when it has been loaded into a project because the text is static.
Label
Places a data field in text format that specifies various parameters when a titleblock is loaded into a project. The standard titleblock label parameters are Project Name, Project Number, Scale, Sheet Name, and Sheet Number. Unlike text, labels change as their parameters change.

Guidelines for Working with Titleblocks Following the recommended practices, you can work effectively with titleblocks.
Guidelines ■
■
■
■
■
Create a titleblock for each size of paper that your company uses when plotting document sets. For example, you can include a letter-size titleblock for use as a fax page or a quick single-page printout. You can load each titleblock size into your company project template files so that they are readily available. Using preloaded titleblocks saves considerable time for the design team members. Create titleblock styles that visually represent each phase of the design development process and switch between styles as the project develops. This practice helps in maintaining better workflow. You should follow this guideline if your company differentiates between the phases of a project, such as Schematic Design, Design Development, and Construction Documentation. Load an alternate titleblock into a project that is not included in the default project template by using the Load Family option. This practice saves time because you do not need to re-create the titleblock each time. Place a titleblock on a sheet by dragging it from the Project Browser. You can also place a view on a sheet in this way. Dragging titleblocks and views onto sheets speeds up the process of creating sheet sets. Create custom labels if you know how to set up and use shared parameters. Custom labels make titleblocks more informative and well-organized.

About Sheets Revit enables you to create sheets to hold model views. You place model views on a sheet to create a document set. After placing model views, you can modify the view or edit the model in the viewports on the sheet according to your requirements.
Definition of Sheets Sheets are project views on which you place building model views, such as plan, elevation, section, 3D views, schedules, and legends. The views placed on a sheet are instances of the views in the Project Browser. Therefore, when you modify a view on a sheet, the changes are automatically applied to the original view in the Project Browser.
Sheet views listed under Sheets (All) in the Project Browser
Viewport Properties A viewport is a rectangular boundary around a view placed on a sheet. Each viewport has an identifying title below the rectangular boundary that displays the view name, view scale, and a detail number. After placing a viewport on a sheet, you can align its title by dragging it to an appropriate position. By default, the viewport titles stay aligned with the viewport when the viewport size changes. You can control the display of viewport titles and create viewport types without titles. In addition to moving a viewport title, you can set the viewport type properties of the title, such as horizontal line weight, pattern, and color. You can also modify viewport instance properties to change the appearance of a view on a sheet.
204
■
Chapter 15: Construction Documentation
The following table describes the viewport instance properties that you can modify. Property
Description
Rotation on Sheet
Rotates a view by 90 degrees either in the clockwise or counterclockwise direction.
View Scale
Specifies the scale or appearance of a view.
Detail Level
Controls the level of detail in the model view.
Detail Number
Controls the number inside the view title bubble.
Model Graphics Style
Specifies the display style of a view to hidden line, wireframe, shading, or shading with edges.
Underlay
Controls the display of an underlay in a plan view.
View Name
Controls the name of the model view in the Project Browser.
Title on Sheet
Controls the name of the viewport that appears on the viewport title bar.
Activating and Deactivating Viewports You can activate a viewport placed on a sheet and work on the building model in that view while the sheet is inactive and visible in the background. Activating a viewport is necessary for modifying a view directly from the sheet. You can activate a viewport by selecting it and using the Activate View option on the Sheet Composition panel of the View tab. You can also activate a view from the viewport shortcut menu. You can activate only one view at a time on a sheet. To deactivate an active view after making the required changes, you can use the Deactivate View option on the Sheet Composition panel of the View tab. You can also deactivate a view from the viewport shortcut menu.
Example of Sheets The following illustrations show various sheets.

Select a standalone or a networked printer and specify the print options, such as paper size, orientation, and print quality. You can also print the sheet to a file by selecting an electronic output format listed in the printer list. Specify the print settings. Specify the print settings, such as zoom and hidden lines, in the Print Setup dialog box. You use these settings to highlight specific aspects of a building model. Preview or print the sheet. Preview the sheet after specifying the print range as the current window or the visible area of the current window. You can also specify a selection of views or sheets to print using the View/ Sheet Set dialog box. Then, print the selected sheet or view. You can also save the print setup to be used later in a project. Note: The Preview option is disabled when you select the Selected Views/Sheets option in the Print dialog box.
Guidelines for Working with Sheets Following the recommended practices, you can work effectively with sheets in a project.

Create and carefully name several copies of views for different design and documentation purposes, for example, Ground Floor HVAC Plan and Ground Floor Electrical Plan. Naming each copy of the view carefully is necessary because you can place a view, other than legends, only once on a sheet set. Moreover, a viewport name on a sheet can be different from the view name in the Project Browser. Creating and meaningfully naming views enables your project team members to easily locate design views both on sheets and in the Project Browser. Create viewport types that do not display the title or extension line or use custom line types. For example, if you place a 3D view or a rendered image on a sheet as an illustration, the view does not typically need a detail number; therefore, you set that viewport type not to show a title symbol. Controlling the title status enables you to quickly build complex pages. Create sheet views without titleblocks by deleting the titleblock after creating a sheet. Sheet views without titleblocks can be used to place illustration views for printing or exporting to image formats. Create sheets using your organization’s project templates and place views on the sheets at an early stage in a project. The sheets and viewports update automatically as a model develops, and you can print sheets at any time. Predefined sheet sets in project files save time and promote design accuracy. Save multipage print setups as part of project templates. These setups can be calibrated to different project stages. For example, when a project is in a design development stage, the concept design setup might only print 3D views. The use of print setups saves time and reduces waste because it ensures that prints match your organization standards.

Lesson: Creating and Modifying Families This lesson describes how to create and modify families. You begin the lesson by learning about families and connectors. Next, you learn the process of creating families and some recommended practices for creating and modifying families. The lesson concludes with an exercise on creating an air terminal family. Families are the basic building blocks of Revit. They include elements and components ranging from diffusers to diesel generators. The appropriate family and its content are essential for creating a design in Revit MEP. With multiple manufacturers creating specific content with usable connectors and parameters, it is now possible to create a complete MEP building information model.

Chapter 16: The Family Editor (Optional)
About Families Revit MEP provides different methods of geometry creation that you can use when you define families. You can combine these methods to create a family. The geometry forms available are lines, extrusions, sweeps, blends, swept blends, revolves, and regions. You can also add text and tags to families.
VAV Unit - Fan Powered - Series Flow family
Definition of Families A family groups elements with a common set of parameters, identical use, and similar graphical representation. You use the Family Editor to create families. The settings in the Family Editor affect a family in a project based on the family category and subcategory. For Revit MEP, the content in the families requires connectors to be intelligent Revit MEP components. If you create families with components without connectors, you cannot use the families in system creation.
Lesson: Creating and Modifying Families
■
217
In Revit, there are three types of families: Loadable, System, and In-place. The following table describes these types. Family
Description
Loadable
These families are created in the Family Editor and can be loaded into a project file.
System
These families cannot be opened in the Family Editor. However, these families have specified parameters that can be manipulated in a project. You can transfer these families between projects. Examples of System families are duct, pipe, and walls.
In-place
These families are created in a project in the context of a custom element with unique geometry that is not intended for reuse.
References Planes Reference planes are used to define relationships among the geometric components within the Family Editor. Reference planes are not displayed when a family is used in a building model, unless a defined relationship between a reference plane and geometry exists, for example, in the centerline of a hot water heater.
Template Properties Family templates are preset groupings of parameters and views that aid in the creation of systemspecific families. After you select a template, Revit MEP starts the Family Editor and opens the commonly used views for that family creation. The template also includes common references that are required to create a family. The common references include reference planes to define the origin and sketching references, common dimensions to help capture design intent, and any solid geometry needed or commonly used to complete the family. The family template files are available in the Imperial Templates (Metric Templates) folder. The following table describes the different types of family templates.
218
Family Template
Description
Wall-based
The wall-based template is used for components inserted into walls. Wall components can include openings so that when you place the component on a wall, it also cuts an opening in the wall. Some examples of wall-based components include doors, windows, and lighting fixtures. Each template includes a wall; the wall is necessary for showing how the component fits in a wall.
Ceiling-based
The ceiling-based template is used for components inserted into ceilings. Ceiling components can include openings so that when you place the component on a ceiling, it also cuts an opening in the ceiling. Examples of ceiling-based families include sprinklers and recessed lighting fixtures.
Floor-based
The floor-based template is used for components inserted into floors. Floor components can include openings so that when you place the component on a floor, it also cuts an opening in the floor. An example of a floor-based family is a heating register.
■
Chapter 16: The Family Editor (Optional)
Family Template
Description
Roof-based
The roof-based template is used for components inserted into roofs. Roof components can include openings so that when you place the component on a roof, it also cuts an opening in the roof. Examples of roof-based families include soffits and fans.
Non-hosted
The non-hosted template is used for components that are not host dependent. A non-hosted component can appear anywhere in a model and can be dimensioned to other non-hosted or host-based components. Examples of non-hosted families include VAV boxes, columns, and valves.
Face-based
The face-based template is used for creating workplane-based families that can modify their hosts. Families created from the template can make complex cuts in hosts. Instances of these families can be placed on any surface, regardless of its orientation. It is recommended that all families be created using the face-based template for working in a linked environment so that when there is an architectural design change, the plumbing fixtures that are hosted to the wall move with the wall.
Hosting Behavior When creating a family using a template, it is important to consider the type of hosting behavior you want for the family. For example, you may want that a new lighting fixture be hosted on the ceiling. However, there may be cases where you want to use that family in wall mount configuration or as a freely suspended family. You cannot change the hosting of a family after it is created. The hosting setting is predefined based on the template from which the family originated. Plane hosting enables the family to be hosted by walls, floors, or ceilings and provides a high level of flexibility. Plane hosted elements move with their hosting elements through linked models. Non-hosted families are hosted by the level they are inserted in and enable the element to be placed anywhere. Their height is defined relative to their level, but there is no association established with elements, linked models, or otherwise. When using linked files, only face-hosted families can be hosted by the linked file’s geometry.
When using linked files, wall-, ceiling-, floor-, and roof-hosted elements are not used because these elements do not recognize the host from the link.

Example of Families The following illustrations show various types of families.

Non-hosted cooling tower
Connectors Connectors are an important part of Revit MEP because they allow data to flow between elements. The discipline assigned to a connector determines the types of systems with which it can interact and how it interacts with other system components.
Types of Connectors There are three basic types of connectors, also known as domains, that can be added to a family. These types are the HVAC, piping, and electrical connectors.
220
■
Chapter 16: The Family Editor (Optional)
The following table describes the three types of connectors. Type
Description
HVAC
These connectors are associated with ductwork, duct fittings, and other elements that are part of the air handling systems for a building.
Piping
These connectors are used for piping, pipe fittings, and other elements that are required for transmitting liquids, steam, gases, and other fluids within a building.
Electrical
These connectors are used for any type of electrical connections within a building. Electrical connectors are considered to be logical connectors rather than physical connectors. This is because even though the software does not support elements such as conduit or cable tray, these elements can still be added but not physically connected to the electrical elements.
Selecting the correct connector is critical to the content working correctly. This is because after a selection is made, it cannot be changed. Any connector that is placed must be deleted and re-added to change the domain or the placement method.
Electrical When a component with an electrical connector is selected, a contextual tab for that category of that family displays. This tab contains tools that allow you to create a specific electrical system such as Power, Data, Telephone, Fire Alarm, Nurse Call, and Communications.
Tools for creating different types of electrical systems
Duct When a component with a duct connector is selected, a contextual tab displays tools that allow you to create a specific HVAC system, such as Supply Air, Return Air, and Exhaust Air.
Tools for creating different types of duct systems

Hydronic When a component with a hydronic pipe connector is selected, a contextual tab displays tools that allow you to create a specific hyrdonic piping system, such as Supply, Return, and Other.
Tools for creating different types of hydronic piping systems
Plumbing When a component with a plumbing pipe connector is selected, a contextual tab displays tools that allow you to create a specific plumbing system, such as Domestic Hot Water, Domestic Cold Water, and Sanitary.

Chapter 16: The Family Editor (Optional)
Options for Placing Connectors You can place connectors using two options, Place on Face and Place on Work Plane. The following table describes the two options for placing connectors. Option
Description
Place on Face
This option maintains a point at the center of the extrusion. Typically, the Place on Face option is easier to use and is suitable for most cases. Using this option, you specify a plane and use dimensions to constrain the connector to the desired location.
Place on Work Plane
This option allows placement of the connector on a selected plane. This option requires additional parameters and constraints to be used effectively.
Process of Creating Families Creating families is a critical task because after the template has been selected and the geometry created, the basic options in the family are programmed into the family and cannot be changed.
Process: Creating Families The following illustration shows the process of creating families.
The following steps describe the process of creating families. 1. 2.
Open a new family. Open a new family by selecting New > Family from the applications menu. Select a template. By default, Revit opens the Imperial Templates (Metric Templates) folder. Select a template to define the hosting of a component. Templates also define the type of family, such as annotation, model, titleblock, or profile.
Lesson: Creating and Modifying Families

223
3.
Create reference planes. Create the reference planes using the Reference Plane tool on the Datum panel of the Create tab in the Family Editor. Specifying the reference planes with properly labeled dimensions to create parametric families is the key to creating reusable families. Reference planes are also used as alignment points. Create extrusions. Create extrusions or the geometry of a component that will be part of the family. The options for creating geometry include sweep, sweep blend, revolve, blend, and basic extrusion.
4.
Note: Associate the geometry that is being created with the reference planes so that when the family is flexed, the geometry is updated. Place connectors. Place connectors, keeping in mind the flow of information through the system. Create separate extrusions for duct and piping connectors.
5.
Note: Electrical connectors are not physical connectors with the ability to draw conduit; these conductors can simply be placed on any face of an extrusion.
Guidelines for Creating and Modifying Families Following the recommended practices, you can work effectively with families.
Guidelines ■

■
224
Avoid creating all details in 3D. Adding too much geometry to a family reduces the performance of the Revit project. Utilize the resources at Autodesk® Seek, which is an online collaboration of multiple manufacturers and Autodesk® that hosts free manufacturer-specific content that is approved and authorized by both the manufacturers and Autodesk. The website for Autodesk Seek is www.seek.autodesk.com. It is also possible to search Autodesk Seek from within the Revit session by selecting the Insert tab and entering the search string. Create a keyboard shortcut to automatically open the Load Family dialog box. Alternatively, click Load on the Options Bar for most component types such as Mechanical and Electrical Equipment when the discipline-specific equipment tool is selected in the Model panel of the Home tab. Creating a shortcut to load families increases the speed at which they can be placed, modified, and scheduled. Duplicate and modify a similar existing family to suit the custom design requirements instead of creating a new family using a template. This saves you time and effort on a project. Lock all extrusion ends to any surface that they must move with. Test this by varying the surface position or host dimensions. Locking extrusion ends ensures that when a family is flexed, the extrusions automatically flex with the reference planes. This helps to create parametric geometry that can be manipulated and reused. Dimension the depth of extrusion for all extrusions that must maintain constant depth or where depth is to be parametrically controlled. This enables you to change the appearance of parametric geometry without editing the family in the Family Editor. The appearance is updated immediately in the project.
