Get Corner Points of a Reference Plane Example (C#)

This example shows how to obtain the 4 corner points of a reference plane.

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

// Preconditions:

// 1. The specified file exists.

// 2. Ensure that the namespace and partial class name in the sample

//    match those of your project.

//

// Postconditions:

// 1. A 3DSketch1 containing 4 corner points of the reference plane is created.

// 2. The Immediate Window displays the coordinates of each corner point.

//

// NOTE: Do not save the part as it is used in a SOLIDWORKS tutorial.
