True Position Callout with Basic off of Non-Datum?
Good afternoon everyone. I have a print I'm hoping to get some clarification on. There is a hole with a true position callout of [Ø|.014(M)|A|B]. If we consider datum "A" to be the bottom of the part, one of the basic dimensions is referencing the top of the part (with the 2nd basic dimension referencing datum "B"). Is this correct, and if so how does the hole get inspected when the top of the part is just sheet tolerance to datum "A"?
Thanks in advance for any and all replies!
