"Webb16 nov. 2024 · Similar to flatness, surface perpendicularity measures surface variation between two parallel planes. But unlike perpendicularity, flatness (like all other form controls) applies to a surface without a datum. Another difference is that perpendicularity controls the angle (90° with respect to the datum feature) while flatness does not. " - Profile of a surface vs flatness
