Replace Component Example (C#)

This example shows how to replace all instances of a component with a different component.

//-------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\assem1.sldasm.
// 2. Select testpart1<1> in the FeatureManager design tree.
// 3. Verify that the specified part exists.
// 4. Open the Immediate window.
//
// Postconditions:
// 1. Replaces all instances of the selected component with the
//    specified replacement component.
// 2. Examine the Immediate window, FeatureManager design tree,
//    and assembly.
//
// NOTE: Because the assembly is used elsewhere, do not save
// changes.
