Create Fill Pattern Example (C#)

//--------------------------------------------------------------------------
// Preconditions: Ensure the specified part exists.
//
// Postconditions:
// 1. Extrudes a hole in the middle of the block.
// 2. Creates a circular fill pattern of the specified hole.
// 3. Inspect the graphics area and the FeatureManager design tree.
//
// NOTE: Because the model is used elsewhere, do not save changes.
