WebApr 11, 2024 · The datum symbol is compatible with all GD&T symbols except for those related to form tolerances (flatness, straightness, for example). To further drive the point home, consider this very easy example. Suppose you drew a rectangle with a hole at its center. Now, you want to check how off-center you drew the circle. WebA flatness requirement is just checking that the surface falls within two parallel planes, xx distance apart. So, if you check it and find it out of tolerance, it is acceptable to adjust to level the part. If it is now in, it is a good part. A flatness is just a check of the form of the surface to itself.

WebLet R be a commutative Noetherian ring with unit. A map f: M → N of R -modules is injective/surjective iff the associated map f p: M p → N p on the localization is injective/surjective for every prime ideal p of the ring R.
