Create Local Sketch-driven Pattern Example (C#)

This example shows how to create a local sketch-driven pattern feature.

// Preconditions:
// 1. Verify that the specified assembly document to open exists.
// 2. Open the Immediate window.
// Postconditions:
// 1. Opens specified assembly document.
// 2. Creates a sketch for the local sketch-driven
//    pattern.
// 3. Selects an assembly component and the just-created
//    sketch for the local sketch-driven pattern.
// 4. Creates local sketch-driven pattern.
// 5. Gets values and settings of the local sketch-driven pattern.
// 6. Examine the Immediate window and graphics area.
// NOTE: Because this assembly is used elsewhere, do not save
// changes.
