Composite Tolerance

I am having trouble understanding composite tolerance, especially when it comes to a bolt hole pattern like this. I am wondering how you would dimension these true positions. Here's my idea using legacy dimensioning:

Level and translate to A, rotate to B, and report the position of 1 hole (any hole?...lets say the 12'O'Clock hole) and give it a .001 tolerance. Then, would I stay leveled to A&B, translate to the hole that I just reported on (12'O'Clock hole), and report the positions of the rest of the holes with a .0005 tolerance?

Thanks so much...I prefer to use legacy...

Lukas No, that isn't the correct approach. It's pretty difficult to validate composite position callouts using legacy because you need to perform various best-fit alignments - and even then, it's not always possible to fully achieve the design intent.
