Get Edge Chamfer Distances Example (VBA)

This example shows how to get the distances of the edges and vertices for the chamfer feature.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Verify that the part document to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the specified part document.
' 2. Creates a chamfer feature.
' 3. Examine the Immediate window for the chamfer data.
'
' NOTE: Because this part document is used elsewhere, do not
' save any changes.
