Expand or Collapse FeatureManager Design Tree Nodes Example (C#)

This example shows how to traverse, expand, and collapse the nodes of a FeatureManager design tree.

//---------------------------------------------------------------------------
// Preconditions: Open a part or assembly document.
//
// Postconditions:
// 1. Inspect the Immediate window.
// 2. All of the FeatureManager design tree nodes are expanded.
// 3. Collapse all nodes.
