Get Chamfer Distances Example (VBA)

This example shows how to get the distances associated with the selected chamfer.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Open a part document that contains at least
'    one chamfer feature.
' 2. Select a chamfer feature.
' 3. Open the Immediate window.
'
' Postconditions: Examine the Immediate window for
' the chamfer data.
