WebMar 18, 2024 · Straightness tolerance is a 2-dimensional GD&T callout that controls the straightness of part features. No axis can be perfectly straight. The goal is to ensure it is straight enough for the application. This callout sets a standard on how straight a feature must be along its length. Straightness can control two very different types of functions. WebJan 21, 2010 · Flatness 0.1/75x75 means that every 75x75 square portion of the surface has to be inside tolerance zone, that is two parallel planes 0.1 apart.
