Get and Set Document Units Example (C#)

This example shows how to get and set document angle units.

// Preconditions:
// 1. Open a part document.
// 2. Open an Immediate window.
// Postconditions:
// 1. Observe the document's angle unit properties in the Immediate window.
// 2. Modifies the decimal places and type of the angle unit.
