Thank you everyone. Just as DY mentioned, the second angled plane is not true to the original three planes because it is constructed from an angled plane. I was trying to visualize this scenario when explaining it to my co-workers. The three point plane method proves it graphically.
Thanks...
Did a search but did not find what I am looking for. In a solid, I would like to create a cutout (say round hole) at a compound angle...say 10deg from xy and 10deg from xz. I created a sketch line in xy..then attached a coordinate to it's endpoint. Then edited the angles of the coordinate...
