Starting a Piping Drawing

1

In this tutorial, you learn how to create part of a piping system for a research laboratory. In the process, you learn the primary concepts of how to use AutoCAD® MEP to draw piping systems and produce construction documents. In this lesson, you learn how to start a drawing. You also learn how to work with projects and insert reference drawings.

Using This Tutorial This tutorial is divided into lessons, each of which addresses a particular task. Each lesson contains step-by-step exercises you can perform to achieve the goal of the lesson. Drawings, referred to as datasets, are included in the project files. You must extract the project files in order to complete any part of this tutorial. You can complete the tutorial from beginning to end or, if you are an experienced user, you can proceed to a specific lesson. The lessons in this tutorial are designed to build upon your knowledge of AutoCAD. If you are not familiar with basic AutoCAD functions and commands, see the AutoCAD Help. These lessons also assume you are familiar with basic AutoCAD MEP features such as tool palettes, the Properties palette, and AutoCAD MEP snaps. If you are not familiar with these features, see “Getting Started” in the AutoCAD MEP Help.

Extracting the Project Datasets You must extract the project files in order to complete any part of this tutorial. If you edit any of the project files, you can extract the files again to reset the project to its original state. You can search My Documents\Autodesk\MyProjects to see if the Research Laboratory dataset has already been extracted.

1

NOTE This tutorial references Windows XP file paths. If you run Windows Vista, they might be different. To extract the project datasets, go to http://www.autodesk.com/autocadmep-tutorials. Locate the tutorial ZIP file for your language; for example, the English language version of the tutorial files is english_tutorials_AutoCAD_MEP_2009.zip. Follow the steps in the corresponding readme.txt file to download the ZIP file and extract its contents to your hard drive.

Working with Metric Content This tutorial requires that the Global content pack be installed as part of the AutoCAD MEP installation for your workstation. The Global content pack is made up of metric content, metric templates, and an AutoCAD MEP (Global) user profile. While you may be accustomed to using imperial units in your day-to-day work, the lessons in this tutorial cover all of the same tasks necessary for you to complete designs and create construction documents using either metric or imperial units.

Verifying the Current Profile In order to complete the tutorial, you must have your current profile set to AutoCAD MEP (Global). To check the profile setting, in AutoCAD MEP click

2 | Chapter 1 Starting a Piping Drawing

Format menu ➤ Options. The name of the current profile is indicated at the top of the Options dialog.

If AutoCAD MEP (Global) is not the current profile, select it from the list and click Set Current. If AutoCAD MEP (Global) is not listed as a choice in the Options dialog, this means that the Global content pack was not installed when AutoCAD MEP was installed on your workstation. To add the Global content pack to your AutoCAD MEP installation at any time, rerun the installer, and select the Add or Remove Features option. To rerun the installer, open the Add or Remove Programs dialog in the Control Panel, and click Change/Remove. For more information, refer to the online AutoCAD MEP installation guides. If you installed a shortcut for the Global profile, double-click the shortcut to launch AutoCAD MEP with the Global profile set as current.

Lesson 1: Starting a Drawing In this lesson, you learn how to configure a project and use Project Navigator to start a drawing. You also learn how to reference a floor plan drawing in a current drawing.

Exercise 1: Specifying a Project First, you specify a project using Project Browser. After you specify the current project, you use Project Navigator to create directories for the AutoCAD MEP drawings. Specify the current project 1 If you do not have a drawing open, click QNEW Standard toolbar to create a drawing.

on the

2 On the Workspaces toolbar, specify Piping.

3 Open Project Browser using one of the following methods: ■

On the Navigation toolbar, click Project Browser

■

Click File menu ➤ Project Browser.

.

4 In the lower-left corner of Project Browser, click New Project . 5 In the Add Project dialog, enter 1 for Project Number, enter Piping Sample for Project Name, and click OK. In Project Browser, the new project is highlighted to indicate that it is the current project. The right pane contains an HTML page.

4 | Chapter 1 Starting a Piping Drawing

To facilitate sharing project information, you can create and store HTML pages in the project location.

6 Click Close. The Project Browser is closed, but the project is still active until you change to another project. When you start AutoCAD MEP the current project is the last one specified before the software was closed. The Project tab on Project Navigator displays general project information.

Exercise 1: Specifying a Project | 5

Use Project Navigator 7 To add a level, click Edit Levels.

8 In the Levels dialog, click Add Level

.

9 To edit values, such as floor elevation or height, click in the field, and enter the desired value.

You assign construct drawings to floors, and then use those floor assignments when creating view drawings. 10 Click OK.

6 | Chapter 1 Starting a Piping Drawing

11 Review the other tabs on Project Navigator, which are used to manage different types of drawings. ■

Constructs are drawings that model a unique portion of a building system. For example, a piping plan for one floor can be a construct. You create constructs of building plans, then reference them onto views and sheets to create construction documents. Because the views reference the constructs, and the sheets reference the views, you only need to modify the construct drawings. Views and sheets are updated either automatically, or by regenerating a view.

■

Views comprise one or more constructs that show a specific view of a building. For example, you can create a view of a piping plan for an entire floor. You can create general views, detail views, and section/elevation views.

■

Sheets are construction documents or presentation documents that contain fully-annotated views and details. They are generally plotted or published to DWF™.

12 To minimize Project Navigator automatically to make more room for drawing space, click Autohide.

When you move the cursor off Project Navigator, it minimizes so that just the title bar is visible. To open it, move the cursor over the title bar. Create a Piping constructs directory 13 Click the Constructs tab. 14 Select the Constructs directory, right-click, and click New ➤ Category. 15 Change the name of the new category to Piping.

Exercise 1: Specifying a Project | 7

In this exercise, you learned how to create a project and use Project Navigator to specify floor levels. You also created a new construct category.

Exercise 2: Specifying a Template A drawing template contains information such as layer, object style definitions, system definitions, and display settings. Template files are specified in the project settings. View the default template for the project 1 Click the Project tab in Project Navigator. 2 In the Current Project heading, click Edit Project.

3 In the Project Properties dialog, expand Templates. 4 Move the cursor over the field next to Common Model/View Template. A tooltip displays the complete file path. This is the default template you use when starting a new construct drawing. 5 Click OK. Create a new construct drawing 6 In Project Navigator, click the Constructs tab. 7 Under Constructs, select Piping.

8 | Chapter 1 Starting a Piping Drawing

8 Right-click, and click New ➤ Construct. 9 In the Add Construct dialog, click in the field for Name, and enter Piping Sample. 10 Move the cursor over the Drawing Template field to view the full file path. This is the default template specified in the project settings. 11 Select Level 0 to assign the construct to the first floor.

12 Click OK. The new construct drawing is added to the Piping category under Constructs. When you create a new construct drawing, it is not automatically opened in the software. You can open a new drawing from Project Navigator by double-clicking the drawing name. TIP In addition to creating a new drawing from the Constructs tab, you can also add an existing drawing to a project. Open the drawing, right-click the construct category where you want to place it, and click Save Current Dwg as Construct.

Exercise 2: Specifying a Template | 9

In this exercise, you learned how to use a template to create a new construct drawing.

Exercise 3:Viewing Configuration Settings In Project Navigator, you viewed project settings such as building levels, elevations, and templates. In this exercise, you view other important configuration settings, such as routing preferences, pipe preferences, and system definitions. These settings control how your systems look and function in the drawing. Open a new construct drawing 1 In Project Navigator, on the Constructs tab, expand Piping. 2 Double-click Piping Sample to open it. Next, you view layer key settings for objects. Layer keys are used to add layers automatically as you draw systems. You do not need to create layers as you draw. View layer key settings 3 Click Format menu ➤ Layer Management ➤ Layer Key Styles. 4 In the left pane of Style Manager, click Global-Descriptive (256 Color) (MEP). 5 In the right pane, click the Keys tab.

10 | Chapter 1 Starting a Piping Drawing

6 Scroll to Pipe.

The layer specified is H-Pipework-G. The template you specified for this drawing, Aecb Model (Global), contains a custom, descriptive layer key system. The first part of the layer name indicates the discipline, the second part indicates the element, and the last part indicates the data type. For the H-Pipework-G layer name, H indicates HVAC, Pipework indicates the part, and G indicates the data type is graphics. Because this layer standard is descriptive, the element is described rather than assigned a code. Layer keys are configured for parts and systems. When you add a part, you specify a system for it before placing it in the drawing. The layer on which the part is placed is based on the part type and system definition. For example, you draw a pipe system. You specify Hot Water Service for the system. The pipe segments are automatically placed on the H-HWS-G layer, where HWS indicates hot water service.

Exercise 3:Viewing Configuration Settings | 11

TIP Layer keying allows you to efficiently manage layers in your drawing. For example, you can turn off a layer for a specific system, or use filters to turn off specific objects on the layer. 7 Click Cancel. Next, you view system definitions. These settings control the appearance and function of parts in a system. View system definitions 8 Click Piping menu ➤ Piping System Definitions. 9 In the left pane of Style Manager, under Pipe System Definitions, click Chilled Water - Supply. 10 In the right pane, click the Design Rules tab. Note the layer key. When you assign a system to a component, this setting determines its layer and other settings, such as color and linetype. 11 Click the Rise and Drop tab. This tab specifies the rise and drop style used to display vertical directions in the system. 12 Click the Pipe Size Displays tab. This feature allows you to control the display of pipes based on their size. For example, by default for chilled water supply, any pipes 40 mm or smaller are displayed as 1-line. 1-line pipe displays all pipe as 1-line, and fittings and inline components are displayed as symbols scaled to their actual dimensions. If the graphical 1-line check box were also selected, any pipes 25 mm or smaller would be displayed as graphical 1-line. In graphical 1-line, pipe is displayed as 1-line, and fittings are displayed as schematic symbols. Fittings and inline components such as valves

12 | Chapter 1 Starting a Piping Drawing

plot at the annotation size specified here. This ensures that small components in a pipe system can be viewed on a plot sheet.

This feature is applied to systems, so you need to specify pipe size display settings for each system. You can also turn off a pipe size display configuration by deselecting it. For example, for chilled water, you can deselect the 1-line configuration so that 40 mm pipes display per the display configuration settings. If you are using a display configuration where pipes are displayed as 2-line, the 40 mm pipes, fittings, and inline components display as 2-line. 13 Click the Display Properties tab. This tab specifies general display settings for the system components. You can use it to override the display properties for objects. For example, you can turn off contour lines for pipe, or add a hatching pattern to visually enhance specific pipe systems in the drawing. 14 Click Cancel. Next, you view routing preferences that specify the default parts to use during layout. View pipe part routing preferences 15 Click Piping menu ➤ Routing Preference Definitions. 16 On the left pane of Style Manager, under Pipe Part Routing Preferences, click Generic Threaded & Flanged Steel.

Exercise 3:Viewing Configuration Settings | 13

17 In the right pane, click the Preferences tab to view the routing preference configuration. You specify a routing preference whenever you add or modify pipes. Routing preferences define the parts that are automatically inserted in the pipe run during layout. You can use routing preferences to specify different pipe connection joints depending on the size of pipe being drawn. For example, when you draw pipe runs using the Size Range 1 routing preference shown below, any pipe you draw that is smaller than 100 mm will automatically use the threaded fittings specified here. If you change to a nominal size 125 mm or larger, flanged parts are automatically used.

18 Click Cancel. The last settings you view are for pipe preferences. View pipe preferences 19 Click Piping menu ➤ Pipe ➤ Preferences to open the Pipe Layout Preferences dialog.

14 | Chapter 1 Starting a Piping Drawing

This dialog controls various pipe run settings including how new pipe runs connect with existing pipe objects, rise/run settings that control the vertical rise to the horizontal run, and other settings that control the layout method for labels and flow arrows on pipe segments. Many of these properties are also mirrored on the Properties palette as you draw a pipe run. 20 Click Cancel. In this exercise, you viewed important configuration settings for pipes. You viewed system definitions, which control how the pipes display and function, and you viewed pipe preferences, which control how pipes behave as you draw them. You also viewed pipe display by size in the system definitions, and you viewed a routing preference with different connection types depending on pipe size.

Exercise 3:Viewing Configuration Settings | 15

Exercise 4: Inserting a Reference Drawing In this exercise, you insert an architectural floor plan as a reference drawing. Reference drawings are also referred to as xrefs (external references) in the software. Add an external reference 1 Verify that Piping Sample is the current drawing. If not, double-click it on the Constructs tab of Project Navigator. 2 Open the Project Browser project. Click Close.

and select the Research Laboratory

3 In the Project Navigator, browse to \Constructs\Architecture\Floor Plans. 4 Right-click 2nd Floor, and click Xref Overlay. 5 On the Navigation toolbar, click Zoom Extents

.

The floor plan displays in the drawing window. All elements in the xref floor plan drawing are automatically screened as gray.

When you add an xref drawing, you can attach it or overlay it. For construct drawings, overlays are recommended. If you attach a drawing as an xref, you add all of the reference drawing data to the current drawing. An overlay does not add its drawing data to the current drawing, which can help minimize file sizes. For view drawings, however, it is recommended that you attach xrefs if you want the reference drawing geometry to display on the sheet. It is recommended that you use 0,0,0 for the XYZ insertion coordinates. As you develop construct drawings based on this floor plan, you can xref them into views and other constructs by inserting them at 0,0,0. This maintains accurate locations for each subsequent system designed around the floor plan.

16 | Chapter 1 Starting a Piping Drawing

NOTE When you are working with a Drawing Management project, add an xref by dragging it from the Constructs tab of the Project Navigator onto the current drawing. Xrefs that are not added in this way are lost when the project is refreshed. When you add an xref by dragging it from the Project Navigator onto a drawing, it is attached instead of overlaid, referenced using its full file path, and placed at the X,Y coordinates of 0,0. Its elevation (Z coordinate value) is also updated to a value relative to the host drawing, and it is determined using the elevations of the levels to which the 2 drawings are assigned. In later lessons, you add pipe systems to the west side of the building. Next, you clip the reference drawing to display only the west side in the drawing. This makes it easier to work on this specific portion of the building. Clip the reference drawing 6 Select the floor plan by moving the cursor over any linework, and click. The floor plan is highlighted. 7 Right-click, and click Clip Xref. 8 On the command line, enter n for New boundary. 9 Enter r to define a rectangular boundary. 10 Click outside the lower-left corner of the building to specify the first point of the rectangular boundary. 11 Move the cursor to the second point as shown, and click to specify the opposite corner.

Exercise 4: Inserting a Reference Drawing | 17

The west side of the floor plan is visible, and the east side has been clipped from view.

12 In the Navigation toolbar, click Zoom Extents

.

13 Close the current drawing, and click No when prompted to save the drawing. In this lesson, you created a project and created a new drawing based on a template. You then viewed settings that affect the construction and appearance of your systems. You also added an architectural floor plan drawing as a reference and clipped it so that you could focus on the portion of the drawing you will be working on.
