Get Names of Bodies in Multibody Part Example (VBA)

This example shows how to get the names of the bodies in each multibody part in an assembly.

'-------------------------------------------------
' Preconditions:
' 1. Verify that the specified files exist:
'    * assembly document template
'    * both multibody part documents
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens both multibody parts.
' 2. Opens a new assembly document.
' 3. Adds the open multibody parts as components
'    to the assembly.
' 4. Traverses the components in the assembly and gets
'    and prints the names of the bodies in each
'    component.
' 5. Examine the Immediate window.
'
' NOTE: Because the multibody parts are used
' elsewhere, do not save changes.
