Get x,y,z Locations of Points in Sketch Example (VBA)

This example shows how to get the x, y, and z locations of the points in the selected sketch.

'---------------------------------------------
' Preconditions:
' 1. Open a part.
' 2. Select a sketch.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Gets the IDs of the sketch points in the
'    sketch and their model and sketch point
'    x, y, and z locations.
' 2. Examine the Immediate window.
