Suppose you have a square shaped object and have a profile of a surface callout on it of 0.5... on a gage how would you control this? Basically, I'm asking how you would design a gage to check for the profile control? Anyone have any examples of such gages that control profile?

Belanger, that makes sense to me, thanks a lot. Reading your response in combination with looking into liftruck's link I get it now. Thanks for your help guys.

MadMango, I know the planes need to be .25" apart but where do you position these 2 parallel planes relative to the surface it is applied on?

lifttrucks, thanks for your reply. However, even after reviewing that link, I'm still not sure. In regards to that example you gave in that link, it seems like all that matters is the any point on the surface should not exceed 0.2 (outwards). But then the definition of flatness doesn't make...
