Create Variable Radius Asymmetric Elliptical Fillet Example (VB.NET)

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.
