Get Data for Surface-flatten Feature Example (C#)

This example shows how to create a surface-flatten feature and get its data.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open install_dir\samples\tutorial\api\toaster.sldprt.
// 2. Open an Immediate window.
//
// Postconditions:
// 1. Creates Surface-Flatten1 in the FeatureManager design tree.
// 2. Inspect the Immediate window.
//
// NOTE: Because this part document is used elsewhere, do not save changes
// when closing it.
