Insert Sketch Text and Hole Example (C#)

This example shows how to insert sketch text and a hole at the selected point on a face.

// Preconditions: Open a model document and select a face.
// Postconditions: 
// 1. Creates a hole and inserts the specified text on the

//    face at its point of selection.
// 2. Examine the graphics area and FeatureManager design tree.
