Get Points of Repeating Elements in Table-driven Pattern (C#)

//---------------------------------------------
// Preconditions:
// 1. Verify that the part to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Gets the coordinates of the
//    points for the two repeating elements in the
//    table-driven pattern.
// 2. Examine the Immediate window.
//
// NOTE: Because the part is used elsewhere, do
// not save changes.
