Activate Smart Feature in an Assembly Example (C#)

This example shows how to activate a Smart Feature in an assembly.

// Preconditions: Open public_documents\samples\tutorial\api\testSmartAssembly.sldasm.
// Postconditions:
// 1. Activates Smart Feature holecube-1 and creates two extruded cuts
//    for the selected reference entity.
// 2. Displays Smart Feature holecube-1 in the FeatureManager design tree.
// 3. Creates Smart-Feature1 in component testpart100.
// 4. Expand and examine testpart100 and holecube-1 in the FeatureManager
//    design tree.
// NOTE: Because the model is used elsewhere, do not save changes.
