Get Offset Surface Data Example (C#)

This example shows how to get data for an offset surface.

// Preconditions:
// 1. Open an assembly document that contains a component that
//    has a surface offset feature.
// 2. Select the component's surface offset feature.
// 3. Open the Immediate window.
// Postconditions: Inspect the Immediate window.
