Believe it or not, I've been programming in PC-DMIS for over 10 years now and I still don't understand Work Planes. I've always figured a way around it and told myself I'd learn it later when I had time.
I was having trouble with something today and finally asked a co-worker for help. He saw what I was trying to do, changed the work plane and everything's fine.
keep in mind, that all these planes are dependent on your alignment, NOT the machine axis. If your part sits with Y+ pointing up, then the 'top' workplane becomes Y+ not Z+ like the machine.
