Backup your model

Before we begin, I seriously and strenuously suggest you back up your model.  Don’t do the saveas (which is fine I suppose), but instead use Windows explorer to copy the .DWG and .XML files to a backup location. The VISTA path to these items is C:\ProgramData\Autodesk\C3D 2009\enu\Pipes Catalog\US Imperial Structures\Inlet-Outlet-Custom\

Map the User Parameters to the Application

You may remember the parameters that were handed down when we verified the structure a few sessions ago.  These ‘handed down’ parameters are those that the application uses in it’s controls, and were assigned when we used the Part Configuration Undefined Bounding Shape.  Without these, the structure cannot be modified. These parameters are SHBTh, SHBW, and SVPC, which are the Thickness, Base Width, and the Vertical Pipe Clearance respectively. We used the user parameters (like bThick) to buffer our equations from the application controls, and to make it easier to understand when reading the parameter list.  When we go back to make changes, we can disconnect the application parameters, and toy with our user parameters, and then attach them when we are done.

Let’s set these values before we proceed farther.  Edit the Model Parameters as follows:

SHBTh = 6

SHBW = 24

SVPC = 24

Now we have given something solid to these values, we can map these to the user parameters we created.

bThick = SHBTh

bWidth = SHBW

Now that the parameters have been set, we need to change the bounding shape to be a box.  Right now, the application will only display the structure as a 3D solid, and many styles will not display

this.  To simplify your model in some cases, we need the bounding shape to be a box.
