Get GTol Witness Line Example (C#)

This example shows how to get the witness line of a geometric tolerance frame.

// Preconditions:
// 1. Open:
//    install_dir\samples\tutorial\api\GTolWitnessLine.slddrw

// 2. Rename the namespace to match the name of your C# project.
// 3. Select the geometric tolerance frame.
// 4. Open an Immediate window.
// Postconditions: Inspect the Immediate window for the
// witness line start and end point coordinates.
// NOTE: Because the model is used elsewhere,
// do not save changes when closing it.
