Get Intersect Feature Data Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open a part that contains the following intersecting features:
//    * Boss-Extrude1
//    * Boss-Extrude2
//    * Boss-Extrude3
//    * Boss-Extrude4
//    * Surface-Extrude1
// 2. Add reference, Microsoft.VisualBasic, to the project.
// 3. Open an Immediate window.
// 4. Multi-select Surface-Extrude1, Boss-Extrude3, and Boss-Extrude4 in the
//    FeatureManager design tree and press F5.
//
// Postconditions:
// 1. When the macro stops, inspect the blue intersect regions.
// 2. Press F5.
// 3. Inspect the Immediate window.
// 4. Right-click Intersect1 in the FeatureManager design tree and click
//    Roll Forward.
//
// NOTE: Because the model is used elsewhere, do not save changes.
