Question meaning of dimension and how to measure
(OP)
The attached image represents a generic question relative to dimensioning and measuring a part. Given a "U" shaped part, where the width between the two vertical legs of the "U" is dimensioned, and each leg of the "U" has an angular tolerance where is it appropriate to measure the dimension between the vertical legs?
The attached picture does a much better job of describing my question.

The 90 degree is also keeping it from becoming a parallelogram.

What if both angles measure 91 degrees? Obviously the dimension at B would be larger in this senario. Don't I get all (3) of the tolerances to work with?

The angular dimensions are controlling the perpendicularity to the base. It almost looks like you don't need both angular tolerances but at extremes of the linear tolerance both could come into play.
