Define Graphic Representations for a Part

This task shows you how to create multiple graphic representations for a part. 

Once you have created a  part and specified a type, you can create one or more graphic representations, i.e., create the body of the part. You can define multiple graphic representations when you need to show more than one graphic of the same component. For instance, you may need to show a pipe as "double", which is like a 3D version, as "single", which means represented by a single line, or "envelope", which also includes the working area needed around the pipe or equipment. These three categories are included with this application. A fourth category is also included, "exact", which is normally used for detailed representation and is used mostly for parts. You can create these three graphics of the same pipe and place whichever one you prefer in a document.

Before you create multiple representations you should set up a Graphic Representations file. (See Understanding Project Resource Management for how to do this.) A Graphic Representations file allows you to classify each graphic that you create into a specific category. In addition to the four categories that come with the application and that were described above, you can create categories based on your specific needs.

1. When you create a part as explained in Create HVAC part with specified type, it is given the first classification listed in your Graphic Representations file. In this example it is Double as shown in the illustration below. To start making graphic representations for the part, you will first create a graphic for the Double representation that you have already created. To do this double click on Elbow1 to bring up the Part Design product. (Not all users may have a license for Part Design - contact your system administrator.)


2. Create your part (in this case an elbow) using Part Design. (See Part Design documentation if you need help.) You have now created the Double graphic representation of the part. 

3. To create a second graphic representation, double click on Elbow1 (Elbow1.1) to return to HVAC Design.
4. Click on the Build HVAC Part button to display the Create Part dialog box and click on the elbow to make it active. The buttons at the bottom of the Create Part dialog box will become active.
5. Click on the Manage Representations button . The Manage Graphic Representations dialog box will display.

If you are creating a light part then you will not have a graphic for it. Create a light part, or open a typed part, and click the Manage Graphics Representations button. The following dialog box displays.

Click on the down arrow to select a name for each of the two representations. You can also select the default representation that you want displayed.

6. The Defined column shows which representations exist for the part. If a name has No against it you can create a representation by clicking on No. It will change to Yes and the graphic name will be added to the specifications tree. You now need to create a body for it, as described above.  In the illustration below you can see both double and single representations. The single representation is the white line running through the 3D elbow.

Use the Associate button to change the name you have already assigned to a graphic representation. To do this, select the graphic name you want to change to in the Manage Graphic Representations dialog box, click the Associate button and select the graphic, either in the viewer or in the specifications tree.
7. After you have added one or more graphic representations for that part, return to Part Design to create the graphic, as explained above.
