Create Variable Radius Asymmetric Elliptical Fillet Example (C#)

This example shows how to create a variable radius asymmetric elliptical fillet and get its data.

// Preconditions:
// 1. Open public_documents\samples\tutorial\api\block.sldprt.
// 2. Open an Immediate window.
// Postconditions:
// 1. Creates a variable radius asymmetric elliptical fillet, VarFillet1,
//    in the FeatureManager design tree.
// 2. Inspect the Immediate window.
// NOTE: Because the model is used elsewhere, do not save changes.
