1.1

The scope of the Guide This guide introduces the facilities provided by AVEVA for the creation of Pipe Hangers and Supports and their incorporation into Specifications which make them accessible to other PDMS designers. A key feature of the guide is a hands-on tutorial exercise which is incorporated throughout. This guide does not give step-by-step instructions on how to carry out every specific support design function, since you can access such information as you work by using the on-line help facilities incorporated into the program’s graphical user interface. If you are not yet familiar with the use of the PDMS Design module, it is recommended that you first work through one or more of the discipline-specific ‘getting started’ guides (Pipework Design Using PDMS, Structural Design Using PDMS, etc.) and practise using the various Design applications. You need to be proficient in the use of Design before you try to create hangers and supports for use by others. You also need to be familiar with the main principles of managing Catalogues and Specifications in PDMS databases using the Paragon and Specon modules. This manual assumes that you are familiar with PDMS Design to the level of AVEVA's Basic Training Course. In addition, it will help if you have some knowledge of the PDMS Design Structures applications, and you are advised to work through the tutorial in the manual Structural Design Using VANTAGE PDMS. To use Automatic Drawing Production, you need to be familiar with PDMS Draft.

1.1.1 Intended audience This guide has been written for engineers familiar with hanger design practices, who may or may not have prior knowledge of PDMS.

1.1.1 Assumptions For you to use this guide, the sample PDMS project, Project SAM, must be correctly installed on your system, and you must have read/write access to the project databases. It is assumed that you know:

Introducing VANTAGE PDMS This chapter gives: • •

2.1

an introduction to the structure of PDMS explains the strengths of PDMS

Introducing the structure of PDMS PDMS comprises the following functional parts: • modules • applications. A module is a subdivision of PDMS that you use to carry out specific types of operation. This guide covers the following modules: • Design, which you use for creating the 3D design model An application is supplementary program that has been tailored to provide easy control of operations that are specific to a particular discipline. The applications you will use for support design work in this guide are: • Pipe Hangers & Supports • In Draft, the Automatic Drawing Production application You can switch quickly and easily between different parts of PDMS.

2.2

The strengths of PDMS In VANTAGE PDMS, you have a powerful suite of facilities for the modification, design validation and documentation of logically interconnected steelwork and/or concrete structures. The emphasis is on maximising both design consistency and design productivity: •

•

The design modelling functions incorporate a degree of apparent intelligence that enables them to make sensible decisions about the consequential effects of many of your design choices. This allows you to implement a sequence of related decisions with a minimum of effort. You can incorporate modifications into your design at any stage without fear of invalidating any of your prior work, because data consistency-checking is an integral part of the product. PDMS automatically manages drawing production, material take-off reports, and so on, by reading all design data directly from a

common set of databases, to prevent errors from being introduced by transcribing information between different disciplines. The applications let you check all aspects of your design as work progresses. This includes on-line interdisciplinary clash detection, so the chances of errors and inconsistencies reaching the final documented design are reduced to an exceptionally low level. The applications are controlled from a graphical user interface. This means that all design, drawing and reporting operations are initiated by selecting choices from menus, and by entering data into on-screen forms. For ease of use, many common actions are also represented by pictorial icons. On-screen help is available to assist you whenever you need help.

how to log in to PDMS how to use the windows, menus and forms that comprise the PDMS graphical user interface on-line help.

Logging in This is the first step of the tutorial exercise. If you do not know where the PDMS program is stored on your system, you will have to contact your system administrator at this point.

Exercise begins:

1.

Start PDMS by double-clicking on the PDMS icon. The VANTAGE PDMS Login form that appears requires you to specify a number of details at the outset of your session.

Ignore any entries currently shown in this form. The next section describes how to complete the boxes, and the exercise continues afterwards.

3.2

Using the mouse You use the mouse to steer the graphics cursor around the screen and to select or pick items by using the mouse buttons. The buttons perform different tasks depending on the type of window, and the position within the window, where the cursor is positioned. The appearance of the cursor changes according to the type of display item that is underneath it. The left-hand mouse button has three functions: •

•

•

On a graphical view, clicking the left-hand button with the cursor over a design element results in that element becoming the current element (that is, the design item on which you want to carry out the next operation). In a sequence of menus, dragging with the left-hand button activates the command represented by the highlighted menu option when the button is released. On a form, the effect varies according to what you select.

The middle mouse button is used primarily to manipulate a graphical view; the right-hand button is used to access the menu options specific to the graphical view window. Note:

3.3

the right-hand mouse button menu will henceforth be referred to as the shortcut menu.

Using forms Forms can include any of the following: • • • • • •

text boxes drop-down lists option buttons check boxes scrollable lists action buttons.

Text boxes and drop-down lists are explained below; the remainder are explained later in this chapter.

3.3.1 Using text boxes Text boxes are the areas where you type in alphanumeric data such as names or dimensions. A text box will usually have a label to tell you what to enter.

3-2

Support Design using VANTAGE PDMS Version 11.6

Getting Started

When you first open a form which contains text boxes, the first text-box on the form is current and a text editing cursor (a vertical bar) is displayed in the box. A text-box often contains a default entry (such as unset) when first displayed. Some text boxes accept only text or only numeric data, and entries with the wrong type of data are not accepted. To enter data into a text box: • • •

Click in the box to insert the text editing cursor. Type in the required data, editing any existing entry as necessary. (You may need to delete the existing entry first.) When you have finished, confirm the entry by pressing the Enter (or Return) key. Any text box with an unconfirmed setting is highlighted by a yellow background.

3.3.2 Using drop-down lists Drop-down lists let you choose one option from a multiple selection. The list will usually have a label to tell you what you are setting and will show the current selection. They typically have the following appearance:

To change the setting, click on the down arrow or button face to reveal the full list of available options, then pick the required option. Exercise continues:

2.

Click on the VANTAGE PDMS Login form to make it active.

3.

Give the name of the Project in which you want to work: enter SAM.

4.

Give your allocated Username: enter HANGER. This username has been set up so that you will have Read/Write access to a Catalogue database, as well as to a Design database. This is necessary so that you can add your new template into a Specification at a later stage of the exercise.

5.

Give your allocated Password: enter HANGER.

6.

Give the part of the project Multiple Database (MDB) you want to work in: enter HANGER.

7.

Give the name of the module you wish to use: select Design. Make sure that you leave the Read Only box unchecked, so that you can modify the database as you work.

Getting Started

You must specify which files to load at startup. You can choose either the application default settings (Load from Macro Files) or a customised setup saved during an earlier session (Load from Binary Files). Design templates are stored in a Design database rather than in a Catalogue database, so enter the Design module by loading its appware from Macro Files. When you have entered all the necessary details, the form looks like this:

The PDMS startup display

When PDMS has loaded, your screen looks like this:

As labelled above, the display comprises the following: Title Bar This shows the current PDMS module, and its sub-application if applicable. Main Menu Bar This is the area you use to make menu selections. Main Tool Bar This has a number of icon buttons and drop-down lists that offer shortcuts to a selection common PDMS operations and standard settings. Design Explorer This shows your current position in the PDMS database hierarchy. To move to a different point in the database, you click on the appropriate item in the list. For full details of the facilities offered by the Design Explorer see the PDMS Design online help. 3D Graphical View This is the window in which you display the design model graphically as you build it. A pop-up menu (which you access with the right-hand mouse Support Design using VANTAGE PDMS Version 11.6

3-5

button) enables you to control how the model is represented. This window also has its own tool bar. Status Bar This displays information about the current status of your operations. You can reposition or minimise these windows at any time using standard window management facilities.

3.5

Using menus Menu options in pull-down or pop-up menus can be in any of three formats: Standalone options initiate an action immediately. Options followed by three dots display a form. Options followed by a pointer, display a subsidiary menu that offers a further range of options. Throughout this guide, related selections from menus are abbreviated form using the > symbol as a separator. For example: Select Position>At>Explicit means:

3.6

8.

Select Position from the bar menu.

9.

Select At from the resulting pull-down menu

10.

Move the cursor to the right and select Explicit from the resultant submenu.

Using the tool bar The tool bar is displayed immediately below the main menu bar in the application window. It contains a number of icon buttons which let you carry out common tasks without searching for the options in the menus. The actions of the buttons are explained in the on-line help. If you pause the cursor over a button, a tool-tip pop-up box will remind you of the function of the button. To activate a button, you click on it. Note:

3-6

The tool bar can be switched off, or displayed with larger icons. To do so, select Settings>System from the main menu bar and then set the required options on the resulting System Settings form.

Using the Design Explorer The Design Explorer presents a hierarchical view of the PDMS databases and makes navigating around the Design Database quick and easy. The figure below shows a typical example of the information the Design Explorer displays:

To expand or collapse any branch of the tree, click on the

or

icon.

You can reduce the amount of information the tree displays by ticking the filter checkbox and selecting one of the predefined core filters from the drop-down combo-box list. If you want to narrow the view down even more, you can change the settings in the Explorer Settings, which you can access by selecting Settings>Explorer from the main menu. If you place the mouse-pointer over an element, you will get a ToolTip that gives the element’s name, type, and description; clicking-the right mouse-button while the cursor is over an element will bring up a context menu from which you can choose to perform various actions. What actions are available depend on which DB and module you are using.

Support Design using VANTAGE PDMS Version 11.6

3-7

Getting Started

You can drag-and-drop elements within the Design Explorer to copy them, or you can drag-and-drop from the Explorer to add elements to the 3D view and My Data. The Current Element is highlighted in the tree view and the Current Element will change to follow selections made elsewhere, even if the Explorer is not the active window. If you set the Expand to CE check box in the Explorer Settings, the tree will automatically expand to show the Current Element if it is not currently in view. The Current Element is also the displayed in the History List, which you will find by default on the main menu bar. However, you can undock the History List and have it as a free-floating window. The figure below shows the History List as a free-floating window.

You can make another element the Current Element using the History List by:

3.8

•

typing the element’s name into the combo box;

•

selecting a previously typed in element from the combo-box’s pull-down list. Note that if you dock the window vertically, it will not display the combobox;

•

navigating through the history one element at a time using the backwards and forwards buttons;

•

selecting elements from anywhere in the History List using the drop down lists on the backwards and forwards buttons.

Using the status bar The status bar displays messages telling you what actions the application is carrying out. You should look at it frequently, especially if the system appears to be waiting for you to do something, since it will always prompt you for any input or action which is required to carry out the next step of your current activity. If the prompt lets you repeat a task an unspecified number of times, such as picking a selection of items using the cursor, you must press the Escape key when you have finished to indicate that you are ready to move to the next operation.

More on using forms Forms are used both to display information and to let you enter new data. Forms typically comprise an arrangement of buttons of various types, text-boxes, and scrollable lists. Input to a form is usually via a combination of mouse and keyboard. While you have access to a form, you can change a setting, return to the initial values, accept and act on the current data, or cancel the form without applying any changes, according to the nature of the form. You were introduced to text boxers and drop-down lists in Section 3.3; this section describes the remaining boxes, buttons and lists: • • • •

option buttons check boxes scrollable lists action buttons.

3.9.1 Using option buttons Option buttons are used to select one, and only one, from a group of options. The selection is mutually exclusive, so that selecting one option deselects others in that group automatically. They typically have the following appearance: Option selected Option not selected To change the selected option button in a group, click the required button.

3.9.2 Using check boxes Check boxes are used to switch an option between two states, typically set and unset. Unlike option buttons, they do not interact, so that you can set any combination of check boxes at the same time. They typically have the following appearance: Set Unset

Support Design using VANTAGE PDMS Version 11.6

3-9

Getting Started

3.9.3 Using scrollable lists A scrollable list is displayed as a vertical list of options within the form, with vertical and horizontal scroll bars along its sides. To select an option, click on the line you want. The selected line is highlighted. Some scrollable lists let you make only a single selection, so that selecting any option deselects all others automatically. Other lists let you make multiple selections, with all selected options highlighted simultaneously. You can deselect a highlighted option in a multiple-choice list, by clicking on it again (repeated clicks toggle a selection).

3.9.4 Using action buttons Most forms include one or more action buttons. You use these to tell PDMS what to do with the details you have entered in the form. The common action buttons are: Tells PDMS to accept the current form settings, and closes the form. Cancels any changes you have made to the form, and closes the form. Tells PDMS to accept the current form settings, and leaves the form displayed for further use. Cancels any changes you have made to the form, and leaves the form displayed for further use. Closes the form, keeping the current settings. Some forms contain more specific types of control button which carry out particular command options. The action is indicated by the name of the button (such Add or Remove).

3.10 Responding to alert forms Alert forms are used to display information such as error messages, prompts and requests for confirmation of changes. You should respond by carrying out the task prompted for, or by clicking on the control buttons on the form (usually an OK or Cancel button).

3.11 Using on-line Help Most bar menus end with a Help option. Where available, on-line help gives detailed instructions on how to use the forms and menus from which you control each application. Choosing one of the Help options will bring up the Help window. The picture below shows a typical example of what you will see:

The pane on the right shows by default a clickable image of the main PDMS Design window. If you click on an area of the image, the image will be replaced by text that describes the part of the image you clicked on. The left pane contains a set of tabs that allow you to use Help in different ways. Choosing one of the options described below activates the relevant tab for you so it is at the front when the Help window comes up. The Help option gives you the following choices from its submenu: Help>Contents

This displays the Help window so that you can find the required topic from the hierarchical contents list.

Support Design using VANTAGE PDMS Version 11.6

Help>Index

This displays the Help window with the Index tab selected, so that you can browse for the topic you want to read about from the alphabetically-arranged list. You can locate topics quickly by typing in the first few letters of their title. Help>Search

This displays the Help window with the Search tab at the front so that you can find all topics containing the keywords you specify. Help>About

This displays information about the current operating system on your computer and about the versions of PDMS and its applications to which you have access. Pressing the F1 key at any time will display the help topic for the currently active window. Exercise continues:

11.

Experiment with each of the Help options until you understand the search and navigation facilities for finding specific items of information. Use the Help>On Context option to read the help texts for any forms which you can currently see on your screen.

12.

When you are ready to continue, close any forms which you have been experimenting with as follows: • • •

If a form has a Dismiss button, click this button. If a form has its own menu bar, select Control>Close from that menu. Close any Help windows which are displayed by double-clicking in the control box in the top left-hand corner of each window. Alternatively, select File>Exit from the Help window menu bar.

Do not close the Design Explorer or the 3D View windows, because you will use these in the next parts of the exercise.

You are advised to make full use of the on-line help facilities whenever you want clarification of any operations during the later steps of the exercise.

Introducing PDMS Hangers and Supports The Pipe Hangers & Supports applications form part of a family of engineering design applications for use with AVEVA's PDMS 3D solid modelling plant design system. They enable designers to model pipe supports in considerable detail, from a range of user-configurable standard designs, using an extensive catalogue of support components. Standard supports are issued against standard drawings, and a support schedule may be produced, showing a variety of user-defined data, including parameterised support dimensions. Support creation can include both the structural steel and the hanger components themselves. For example, a goalpost support may consist of three or more steel sections and their joint details, together with spacers and U bolts. A hanger-only support could consist of lug, rod, turnbuckle and pipe clamp. The applications can check all aspects of the design as work progresses, including on-line interdisciplinary clash detection. User customisation can be applied to automatic support numbering and classification.

4.1

Locating the Support A support is first located by positioning a plane in the 3D model. The quickest way of doing this is by identifying the piping to be supported in a graphical view. Support location and orientation can be determined by the position of a piping component, by a distance from a previous support, or by explicit coordinates. Each pipe to be supported is identified, and the hanger type (e.g. grip or non-grip U bolt, clamp, etc.) is chosen for each. In this context, ‘hanger’ is used to mean the component attaching to the pipe, and can include support from above or below. Thus a single support can include a number of hangers: one per pipeline.

4.2

Support configuration Having located the support and identified the supported lines, a basic support configuration is chosen from a set of specification-based standards. These can be user defined, but a sample set is provided, including a one- or two-level goalpost, a braced cantilever, an L bracket, etc. The configuration determines the basic shape and jointing information. It may be standard (with parameterised dimensions) or special. The dimensions of a standard

Support Design using VANTAGE PDMS Version 11.6

Introducing PDMS Hangers and Supports

support template can be changed, but it cannot have extra members added. Special templates can be modified by adding members for further support or bracing, and changes to jointing information or support dimensions.

4.3

Connecting supports Supports may be connected to floors, ceilings, primary or secondary steel. This includes extending members to reach their connections, and providing a connected structural model. Furthermore, a new hanger may be added to an existing support to take an extra line. Once the configuration is complete, steel profiles are selected by choosing from a support steel specification.

4.4

Standard Hanger configurations Supports which have no steelwork (such as a spring hanger with rods and clamps) use standard hanger configurations defined by the Hangers & Supports administrator (a sample set is provided). The designer selects the attachment points on the pipeline and the structure, and chooses the hanger configuration from a specification. All components within the hanger are then selected automatically from a hanger specification, sized, orientated and connected together. Some user interaction may be prompted for if design parameters are required; for example, spring presets.

4.5

Utilities A set of utilities help the support designer to be productive. These include sophisticated copy and move operations, with automatic adjustment of supporting elements to allow for changes in relative pipe positions. For example, a sloping line can be supported by designing the first support, then copying it at desired intervals. Necessary changes in elevation (and thus parameterised dimensions) are accommodated automatically. In addition, a graphical coloured maximum span indication can be shown, based on span tables stored in the catalogue.

4.6

Catalogues supplied with the product A sample vendor Hanger Catalogue is supplied with the application. AVEVA would like to acknowledge the assistance provided by Pipe Supports Ltd (PSL), upon whose range of Comet Pipe Support Systems catalogues this data is based.

Introducing PDMS Hangers and Supports

In addition, a selection of the PSL Variable Effort Supports are also supplied, including Top Suspended (3 types) and Base Mounted (1 type). All spring types and working ranges are covered. The application allows the designer to enter the working load at design time to ensure that correct component sizing takes place for material take-off. The catalogue has full component and material descriptions, ordering codes, and where necessary, details additional components which need to be ordered apart from the main item itself (e.g. locknuts, bolts). A specification will be supplied which includes all the components available in this catalogue.

4.7

Drawing facilities PDMS generates drawings by using live links to the design data to ensure that new drawings always reflect the current state of the progressing design model. As the design progresses, up-to-date industry standard engineering drawings, to international standards, can be created on demand. The Hangers & Supports application for use with Draft provides fully automatic production of annotated and dimensioned fabrication drawings for hangers and supports, incorporating location plans, full material take-off, and support schedules. A range of user customisation options are available, with basic drawing layout being controlled by a user-defined backing sheet. Only minimal user post-processing (such as tidying label positions) is required to complete a drawing. Drawings may be created in either batch or interactive mode.

The hangers and supports database hierarchy The main administrative element for a Support or Hanger is the Restraint (REST). The Restraint name is the name of the support. All Support database elements are linked by references and any part of the support can be traced back to the Restraint: see the diagram below: SITE /DEMO/H&S

REST /P-ABC999-0001

HANG /HANG1

HANG /HANG2

In the Hangers & Supports application, Restraints are created under Zones. The Hangers (HANG elements) are owned by a Restraint. Restraints have a similar function to Pipes, and Hangers have a similar function to Branches. Hangers connect pipework to steelwork or civils. Hangers connect to Fittings (FITT) in the steelwork or civil and ATTAs in the pipework. Restraints contain all the Hanger (pipe-to-steelwork connection) information. Every Support assembly has an associated Framework. The Framework (FRMW) owns at least one Subframework (SBFR): if the Hangers in the assembly are in different planes, you will need to create a Subframework for each plane. The Subframework contains all the steelwork data. Frameworks are owned by Structures (STRUC) or Substructures (SUBS). The examples in this manual are based on the MDB /HANGER, supplied with the product, which contains the following Sites and Zones:

Check that the settings on the form are as given in section 6.1. (If any of them are different then change them accordingly; in particular, the Support Origin may differ, don’t forget to Move the support plane if you have to change its origin.)

35.

Close the form.

36.

If you have not already done so, switch off the display of the support plane by selecting the first icon on the General toolbox. This icon toggles the support plane on and off.

Creating the Framework, and Classification When you create a Framework in the Hangers & Supports Application, a Framework (FRMW) and a Restraint (REST) are created in the areas that you set on the Storage Areas form. Supports are classified according to the type of element they support: for example, Pipes only, Cable Trays, etc. The classification affects how the support is named: with the autonaming rules supplied, the type is shown by the first letter in the name, but this may be changed in your system.

37.

Click the second icon on the Support Creation toolbox:

You must create a Subframework in the Hangers and Support Application before the steelwork Sections for the support are created. There must be a Subframework, positioned using the Support plane, for each direction of pipes which are supported. This is further illustrated in Chapter 8. Note that you can add out-of-plane bracing members to a Subframework, it is the plane of the main supporting members that is defined. The data structure (if you have chose to use the text ABC999 to autoname supports) now looks like this:

Creating Template Members A Support Template contains the right number of stanchions, cross-members and hangers for the configuration and the number of Pipes or other elements to be supported. An N-level goalpost support will be used in this exercise, which will be created with two stanchions and the correct number of cross-members for supporting the Pipes you select. In this case, it will have two cross-members. You will need to create the other stanchions and bracing members separately, but for now you will just create the basic structure.

42.

Navigate to Subframework P-ABC999-0001/SBFR1. Select the fourth icon on the Create Support toolbox. The Create Template Members form will be displayed:

The name of the Support is shown at the top of the form.

Other parts of the form are: • • •

Member Type which defines the type of Member you are going to create (stanchion or cross-member). Member Direction which tells you the direction the Member will have. The direction is determined by the direction of the pipes being supported. Hanger Direction which allows you to set the Hanger Direction. The hanger direction depends on whether the pipes are above or below the crossmember supporting them. See the figure below:

Hanger direction UP

Hanger direction DOWN

The Action list allows you to create and delete Members, and to create Hangers. Once you start creating a Member, the options change to allow you to create Hangers on that member, as described below. Note :

Support Design using VANTAGE PDMS Version 11.6

Creating a Goalpost Support

56.

Within the Specification you have selected, there are three Types of configuration: Goalposts have two stanchions and varying numbers of cross-members. Cantilever supports have one or two cross-members, and optionally a bracing member. L-brackets have a stanchion and one or two cross-members.

You should choose the configuration closest to the one you require. You must define all the members in the template: for example, if you choose a 2-level goalpost you must specify at least two levels of pipes. The Configurations list shows configurations for the selected configuration type. The picture on the form shows a parameterised diagram of the configuration type. The Joint Type under the list shows the joint type for the selected configuration. The Support Type can be set to Standard or Special. You can change the sizes of the members of a standard support but you should not add extra members. When you have configured the support, the parameters will be shown in the text boxes below the picture. You can change them if you need to: this is illustrated in the example in Chapter 8. The Invert and Mirror buttons reconfigure the support, and any members which have been added to the template will be removed. This means that you should orientate the support correctly before adding any extra members to the template. Invert Mirror

changes the stanchion direction (and also the principal direction). changes the cross-member direction (and also the principal

direction). On the Support Configuration form: 57.

Set the Spec list setting to Standard Support Configs.

Checking the Member Connections Before you add extra members to the support template, you should understand how the members of the template are connected to each other. Each member has a Start and an End. Each start and end has a Connection type, which can be Attached, Anchored, Owner or None. The connections between one template member and another are Joints. Each Joint has an Owner and an Attached member. If you are going to add members to a template, the current element must be the element which owns the Joint. Select the member you want to check from the scrolling list of SCTNs, or select the arrow button and pick the member in the graphical view. The information is given on the Check Member Connection form.

Creating a Two-plane Support This exercise illustrates how to create a support for pipes or other items running in two different directions. The Branches which will be supported are SAM-250-1 and SAM-300-1, which run North-South along the West side of the Site and then turn and run West-East along the South side of the Site. • •

You will need to create two Subframeworks, one for each pipe direction. You will need to use a combination of templates to obtain the right number of stanchions. In this case, use a goalpost template for the first Subframework, supporting the Pipes running North-South, and an L-bracket template for the second Subframework, supporting the Pipes running East-West, then join the unattached ends of the L-bracket to one of the stanchions of the Goalpost. See the following diagram:

Automatic Drawing Production The PDMS Draft Hangers & Supports Automatic Drawing Production Utility produces fully annotated and dimensioned engineering drawings of pipe hangers and supports, their associated supported items, and any associated main steelwork sections. All settings needed to define the Hangers & Supports drawings can be saved in one or more macro files, and then the macros can be run as a batch process.

C.1 The Batch Macro Generation Form In the Draft Auto Drawing Production application, select Create>Hanger & Support Drawings. The H&S Batch Macro Generation form will be displayed:

The current defaults file is shown in the Defaults area near the top of the form; the settings defined in this file are loaded automatically when you enter Draft. You can change the default settings by selecting the options on the Default_Settings menu at the top of the form. The Batch Dir/Macro text boxes show the default file in which the drawing parameters will be stored if you save a macro without giving it a name. The Message Dir/File text boxes show the file which will be used as the message file during batch macro execution. When processing has been completed, Structural Design Using VANTAGE PDMS Version 11.6

Automatic Drawing Production

this file will contain a progress report of each drawing production cycle, together with any error messages output. The Log Dir/File text boxes show the file which will be used as the log file during batch macro execution. This file is a standard PDMS alpha log file which records the output response to each macro command line.

C.1.1 The Restraint List The Restraint list defines the content of each drawing. The elements to be processed can be specified in the following ways: • •

By entering an explicit restraint name in the text box. By entering the name of any element which has one or more restraints below it in the design hierarchy. All such restraints will be drawn. • By reference to a Draft drawlist (IDLI) element which includes, either directly or by descent, one or more restraints. In each case, you can navigate to the required element in the Design Explorer and then use the CE button to enter the element name into the text box. Conversely, if you have typed a restraint name into the text box explicitly, you can click -> Rest or -> Drwg to make the Restraint or its associated Drawing the current element. If you have specified a Draft drawlist for the restraint definition, you can modify the list from within the application. To do so, click Modify list and use the Drawlist Management form to edit the list in the usual way (see the Draft online help if you are not sure how to use this form).

C.1.2 Checking Data Consistency It is usual to run data consistency checks on supports when they are created in Design's Hangers & Supports application. If you wish to re-check data consistency you can carry out the same process from within Draft by clicking Check... on the H&S Batch Macro Generation form. The H&S Data Consistency Check form will be displayed. The options are as follows:

C-2

Support Design using VANTAGE PDMS Version 11.6

Automatic Drawing Production

Enter the element to be checked in the Check text box. You can use the CE button or type in the name. The element can be a single restraint or a higher level element above a restraint. To start checking, click Check. Any messages will be displayed in the scrolling text pane. If there are no errors which would affect drawing the restraint, the message NO DATA INCONSISTENCIES will be given. If you want to save the list of messages to a file, select File>Save As from the menu. When the file has been saved, the filename will be shown at the top of the form.

C.1.3 Producing Drawings If you only use the preset defaults, you need only specify the restraint(s) to be drawn and the H&S Drawing Registry in order to generate complete drawings automatically. If you want to change the default settings, see next section. When you have set up all the required formatting defaults and have specified which restraints are to be drawn, you can produce the resulting drawings in either of the following ways: •

If you wish to produce only a small number of drawings, you can initiate drawing production immediately from within the application. You will probably

Support Design using VANTAGE PDMS Version 11.6

C-3

Automatic Drawing Production

find this method efficient only for one-off drawings, since the drawing execution times are longer than those for batch mode. • If you wish to produce many drawings, you can save all the current settings for the content and format of the drawings to a macro file. You can then run the macro file in batch mode to produce the drawings. To generate a drawing of the hangers and supports defined by the current Restraint list, click Process Now on the H&S Batch Macro Generation form. The format of the drawing will be as defined by the current default settings and the drawing will be stored under the Draft Registry defined by the H&S Drawing Registry setting on the H&S Overall Defaults form.

C.2 Setting the Drawing Defaults The format of each drawing is derived from a number of default settings. These will have been defined initially by the Draft Administrator to suit your company's standards, although you can override most of the settings. You can modify the drawing formats using the forms displayed when you select one of the options under Default_Settings on the menu at the top of the H&S Batch Macro Generation form.

C.2.1 Setting the Overall Defaults To view or modify, the overall default settings, select Default_Settings>Overall from the menu bar on the H&S Batch Macro Generation form. You will see the H&S Overall Defaults form:

C.3 Creating and Running Drawing Batch Macros When you create a batch macro for the automatic production of hanger and support drawings, all formatting options (as defined by the current default settings) and all elements to be drawn (as defined by the current restraint list) are stored as variables in the macro. To save the current drawing definitions to a macro file, either select File>Batch>Save Macro to save them to the file shown by the Batch Dir/Macro setting, or select File>Batch>Save Macro As... to save them to a file whose name you will specify using the resulting file browser. When you save the drawing creation commands to a batch macro file, the command lines are checked for validity of the default settings and other batch data. Any errors encountered during the macro creation process are recorded in a form. To view this information after saving the macro, select File>Batch>Display Verify Errors. A batch macro file consists of the commands necessary to create a fully annotated and dimensioned drawing in Draft, using the settings of variables to define the drawing parameters. Each macro ends with a CALLSUP START command which initiates the drawing production macros. You submit each macro for batch execution in Draft in order to create the corresponding Hangers and Supports drawings. If you have no standard method for submitting PDMS batch jobs for execution, bring up the Command Input & Output (Display>Command Line) form, and then execute the batch macro.

C.4 Saving the Defaults To save all of the current default settings to a file, either select File>Defaults>Save to overwrite the current defaults file (as shown by the Defaults File Name) or select File>Defaults>Save As to save them to a file whose name you will specify using the resulting file browser. To load a new defaults file, select File>Defaults>Load From and select the required file using the resulting file browser. The name of the file will be shown in the Defaults area. If you have used the Default_Settings>... menu options to modify any defaults from the settings defined by the current defaults file, you can reset them by reloading the current file. To do so, select File>Defaults>Load. When you load drawing defaults from a file, all settings loaded are checked for validity. Any errors encountered during the loading process are recorded in a form. To view this information after loading, select File>Defaults>Display Load Errors.
