Flatness Tolerance in GD&T - Metal Cutting Corporation
Flatness, then, is a characteristic of a three-dimensional (3D) object as it exists between the two parallel planes that delineate its tolerance zone. Surface straightness, on the other hand, is two-dimensional (2D). Its tolerance zone exists between two parallel lines and is an indicator of flatness along one line on a part's surface.
