Check Interference Among Bodies (VBA)

This example shows how to check inteference among bodies in a part document.

'-------------------------

' Preconditions: Part document is open that

'                contains multiple solid body folders

'                that contain one or more solid bodies.

'                Example works best if one body in a

'                a solid body folder interferes with

'                one or more solid bodies in another solid body

'                folder.

'

' Postconditions: None
