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?
By the looks of your sketch, I would simply switch B and C.
-Level to A axis(5 hit cylinder)
-Rotate to a 2d perp line 'ray line' from a axis to C
-Origin XY to A axis
-Origin Z to B
