Get P-Spline Parameterization Data Example (C#)

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 an Immediate Window.
// Postconditions:
// 1. Gets the P-spline parameter data for the selected curved edge.

// 2. Inspect the Immediate window.
