This example shows how to combine bodies in a multibody part.

' Preconditions:
' 1. Verify that the part document to open exists.
' 2. Open the Immediate window.
' Postconditions:
' 1. Opens the specified part document.
' 2. Selects two solid bodies.
' 3. Inserts a combine feature using the two selected
'    bodies.
' 4. Prints the type of combine feature to the Immediate
'    window.
' 5. Examine the Immediate window.
' NOTE: Because the part document is used elsewhere, do not
' save changes.
