Get P-Spline Parameterization Data Example (VB.NET)

This example shows how to get P-spline parameter data for a selected spline or curve.

' Preconditions:
' 1. Open install_dir\samples\tutorial\molds\telephone.sldprt.
' 2. Select a curved edge of Shell1 in the graphics area.
' 3. Open the Immediate Window.
' Postconditions:
' 1. Gets the P-spline parameter data for the selected curved edge.
' 2. Inspect the Immediate window.
