Is this important?
I would imagine so, considering all the parts have datums, but what is the difference from, say, setting a point as Datum A and dimensioning a feature to Datum A, and setting a point and dimensioning a feature to said point?
As far as I understood it, I can take a point on 1 end of a part, and take a point on the other end. If I want to find out the distance between the two points, it shouldn't matter that 1 is a datum and 1 is not. It should matter that I want the distance between the two points. But if I take a point in the middle of a round flat feature, and another at the top of a father away round flat feature, if I want the distance in Y I would ask for the distance in Y, and it would give me the distance in Y, and setting one or the other or both to a datum wouldn't make a difference because Y is still Y and the points haven't moved.
