Modify Fillet Weld Bead Example (C#)

This example shows how to modify a fillet weld bead..

// Preconditions:
// 1. Open public_documents\samples\tutorial\api\weldment_box3.sldprt.
// 2. Open an Immediate window.
// Postconditions:
// 1. Inspect the Immediate window to see the properties of Fillet Bead1.
// 2. Modifies some properties of Fillet Bead1.
// NOTE: Because the model is used elsewhere, do not save changes.
