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.
