Good afternoon,
How would I go about using Datum A, which is a curved surface to level to? Ais the underside of the part, B is a flat spot on the top side of the part and datum C is a slot on the top of the part.
Sorry but for me you are not right, because in real life curved surface will touch opposite part in 3 highest places, if it is datum A, it will never touch complete surface
if it is a curved surface BY DESIGN, then you have no idea what the 'high' (or 'low') points are unless you measure the 'entire' surface. It isn't like putting it on a flat plate and letting it 'level' to the 3 contact points like for a designed flat surface that came out with curves in it.
