Get and Set Loft's Pick Points Example (C#)

This example shows how to get the pick points of a loft feature.

//---------------------------------------------------------------------------

// Preconditions:

// 1. Open:

// <SolidWorks_install_dir>\samples\tutorial\cosmosfloxpress\ball valve\handle.sldprt

// 2. The feature named 1 (a loft feature) is selected.

//

// Postconditions: New loft pick points set.
