Stop in for a cup of coffee

If I had a CMM machine and the ability to do cutaways on real parts, I would model it...
Speaking of which Karl - We have a proposal for you.
It's much simpler than a full engine. It's one of these little parts for our cars (well some of our cars) that is no longer made.
I'm told that having a CAD or 3D model is better than paper drawings these days.
