[QUOTE="Wes D., post: 6025, member: 771"] This is where I always get lost on talking about tolerance. When I say I want something to be 1 inch long, and I measure it and it is 1.001, I get the tolerance. But how do you specify tolerance on flatness? keeping under 0.0001" of lift or skew across 3 feet is no easy task... ...not that I'd even be able to measure it, if it wasn't. As I mentioned, it is more important that the parts are similar in height, than if they adhere to the dimensions of the drawing. Is this something that can be encompassed in a drawing? Or is it only through conversations like this that these things get sorted out? [/QUOTE]
