Create Ground Plane Example (C#)

This example shows how to create a ground plane.

//------------------------------------------------------------------------------
// Preconditions: Ensure that the specified model exists.
//
// Postconditions: Creates Ground Plane1 in the Grond Planes folder of the
// FeatureManager design tree And modifies it.
//
// NOTE: Because the model is used elsewhere, do not save any changes to it.
