Get Linear Pattern Feature Data Example (C#)

This example shows how to get data for a linear pattern feature.

// Preconditions:
// 1. Open a part document with a LPattern1 feature.
// 2. Open the Immediate window.
// Postconditions:
// 1. Gets, sets, and prints linear pattern feature data to
//    the Immediate window.
// 2. Examine the FeatureManager design tree, graphics area, and Immediate window.
