Displaying a Bend Angle in a Piping Isometric Drawing

This document will outline the steps needed to display a bend angle on a piping isometric drawing. You must use the JSpace Class Editor to modify the ISO_BEND class in the ps_iso.lib class library.

The following steps will guide you through this process.

1. Open the JSpace Class Editor from the Windows Start button, by default Start > Programs > PlantSpace Design Series > JSpace Class Editor.
2. In the JSpace Class Editor open the class library ps_iso.lib, which by default is located in C:\Projects\"project_name"\etc\.
3. In the Class Browser highlight the class ISO_BEND and click the Edit button. (see figure 1)

   Figure 1

4. In the Class Editor dialog box select Relationships in the "List of" pull down menu. (see figure 2) Click on the Add button to open the Relationship Editor.

5. In the Relationship Editor Dialog type ISO_OF in the Name field. (see figure 3)

6. Click the blue button to add a Daemon Expression. (see figure 4) Click the Expression Editor button (also shown in figure 4) to open the Expression Editor (see figure 5) and add the following Expression:
   UPDATE_SELF() then Click OK.

7. Repeat Step 6 to add the following Daemon Expression:
   ISO_ANGLE = "ANGLE " + ( \ISO_OF\ANGLE * 100)

   The Relationship Editor should now show two Daemons as seen in figure 6. Click the Apply button.

8. Save and close the ps_iso.lib file and then close the JSpace Class Editor.
9. Recreate the JSpace Model file using the JSpace MicroStation Connection and then recreate the isometric drawing in ISOGEN. All bend angles should now display on the piping isometric drawing.
