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

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

//-------------------------------------------------------
// Preconditions:
// 1. Verify that the part to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the part.
// 2. Inserts a surface-flatten feature.
// 3. Gets surface-flatten feature data.
// 4. Examine the graphics area and FeatureManager design
//    tree.
//
// NOTE: Because this part is used elsewhere, do not save
// changes.
