Traversing Assembly at Component and Feature Levels Example (VBA)

This example shows how to traverse an assembly at the component and feature levels.

'------------------------------------------------------
' Preconditions:
' 1. Verify that the specified assembly document to open
'    exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Specified assembly document opens.
' 2. Traverses the components and features in the assembly.
' 3. Examine the Immediate window.
