Create Equation-driven Curve (VB.NET)

This example shows how to create and modify an equation-driven curve.


' Preconditions:  Part document is open in SolidWorks.


' Postconditions: A 2D sketch is created, and an equation spline of a

' sine curve is created.  After the break point, the curve is edited

' and a cosine curve is created.
