Get Edge Curve Parameterization Example (VB.NET)

This example shows how to get curve parameterization data for a selected edge.

'-----------------------------------------------
' Preconditions:
' 1. Open a part or assembly.
' 2. If you opened an assembly, ensure that it is
'    fully resolved.
' 3. Select an edge.
' 4. Open the Immediate window.
