Get Labels of Datum Origin Example (C#)

This example shows how to insert a hole table annotation and get some of its properties.

// 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. Prints to the Immediate window:
//   * the hole table's datum origin x and y labels
//   * whether to display hole sizes using ANSI inch letters
//     and drill numbers
// 5. Examine the Immediate window and drawing.
// NOTE: Because the model is used elsewhere, do not save changes.
