Anyone have a good way to control rotary output order? I have some holes to drill on opposite faces of a part. I prefer to only index the B 180 so that the hole positions remain constant instead of indexing A 180. The posted code comes out as A180.

You should be able to use the Lock Axis UDE.
Lock the A Axis. This way the post should force the B axis to move. You may need to chage the Lock plane to get the correct output.
