I don't understand Work Planes

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.

Can someone explain it to me???

  • Too bad Hexagon doesn't bother to spend a little more time on this topic in their training courses (which clearly is important) I got the same problem with iterative & best fit. Too little time to explain concepts that aren't exactly easy to get after one or two examples.
    If you have a part like a cube sitting on the CMM table with its primary datum pointing up if you want to probe holes drilled into its sides you need to change the workplane to either x plus/minus or y plus/minus. Z-plus is always the default.
