Get Mirror Part Information Example (C#)

//---------------------------------------------------------------------------
// Preconditions:
// 1. Open a part that contains a reference plane about which to mirror the part.
// 2. Select the reference plane in the FeatureManager design tree.
//
// Postconditions:
// 1. Creates and mirrors a part about the selected reference plane.
// 2. Shows the reference plane in the graphics area.
// 3. Inspect the Immediate window for mirror part feature data.
