Get Labels of Datum Origin Example (C#)

This example shows how to get the labels of a datum origin.

// Preconditions:
// 1. Verify that the specified files exist:
//    * part document
//    * drawing document template
//    * hole table template
// 2. Open the Immediate window.
// Postconditions:
// 1. Opens the specified part document.
// 2. Creates a drawing of the part document.
// 3. Inserts a hole table annotation at the specified vertex.
// 4. Gets the hole table and its datum origin.
// 5. Prints the datum origin's x and y labels to the Immediate
//    window.
// 6. Examine the Immediate window and drawing.
