I have a part I have to do a iterative alignment on but the print only has 3A,1B, & 1C targets. The rotation is just 1 point on the top of the part on a plane lined up to the centerline of a cylinder on the opposite side. The plane is also called out as the B datum for a True position. Documents are controlled so I can't share it but is there anyway to rotate with only 1 target before I tell them they need to fix the print?
and what kind of tolerances are we talking about here? IMO, and i admit this is my opinion and my opinion only and other may differ. If this is a casting, and it is unmachined, and the tolerances are wide open, I'm taking a few liberties on how I evaluate this part, and that includes possibly adding a few more hits to establish datums and alignments more clearly that what the print suggests. And then I move on with life.
If you are still hesitant to do this, then bring it up to your superiors and ask for suggestions on how to move forward.
