Am I able to remove the Feature Control Frame from the Datum C hole? Or can I remove Datum C altogether and have the Feature Control Frame to Datums A and B only (left side view)? If so, can I add bonus tolerancing from Datum B to the Ø.573/553 holes?
If it is theoertical, I cannot see the logic because you may have the holes out of position to the theoeritcally perfect position, yet they can function together just fine (twist the part to the right, etc.)
