Change Component to Envelope Example (C#)

This example shows how to change a component to an envelope.

//-----------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified assembly to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the assembly.
// 2. Selects the shaft washer-4 component.
// 3. Gets whether the component is an envelope.
// 4. Changes the component to an envelope.
// 5. Gets whether the component is an envelope.
// 6. Examine the Immediate window and FeatureManager design tree.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
