Create Multiple-Radius Fillets Example (C#)

//--------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\box.sldprt.
// 2. Select three intersecting edges on the inside of the part.
//
// Postconditions:
// 1. Fillets the three selected edges using three
//    different radii.
// 2. Examine the graphics area and FeatureManager design tree.
//
// Note: Because the model is used elsewhere, do not save changes.
