@Jacob Cheverie, That all makes sense. What about translating the coordinate system along the direction normal to datum feature A until it reaches the surface the hole is cut into, then rotating the model so datum A plane is parallel to the surface with the hole? I know this seems like it's...
Jacob Cheverie is correct. Thank you for clarifying. Unfortunately drawing changes take a long time to get approved from my customer. Usually I provide a redline print with an alternate datum reference frame making datum B the primary in similar cases.
Is there no allowance or anything to move...
@3DDave
Yes, the datum B surface may only have a couple contact points. Being that datum B is the secondary datum, currently the surface is scanned by the CMM, then the model is constrained by 2 outer tangential contact points on the datum B surface.
This has been causing the model to tilt...
On a Primary datum with a small surface, there is bound to be some amount of error in approximating this plane on CMM. My quality team is telling me there is projection error when evaluating the .030" true position on the opposite end of the part by keeping datum A as primary. The true position...
