Get Library Feature Data Example (C#)

This example shows how to get data about library features in model documents.

// Preconditions:
// 1. Open a model document that contains at least one
//    library feature.
// 2. Open the Immediate window.
// Postconditions:
// 1. Traverses the FeatureManager design tree searching for
//    library features.
// 2. Gets each library feature's data.
// 3. Inspect the Immediate window.
