Traverse Assembly at Component and Feature Levels Using Recursion Example (VBA)

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

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

' Preconditions: Open:

'  <SolidWorks_install_dir>\samples\tutorial\PDMWorks\speaker.sldasm

'  or any assembly document

'

' Postconditions:

' 1. Output of the assembly traversal is shown in the Immediate Window.

' 2. The elapsed time to traverse the assembly is also shown

'    in the Immediate Window.
