WebFlatness in gd&t is a type of foam control GD&T tolerance. It controls the variations in a flat surface, regardless of any datum feature. In this way it ensures the required surface is flat enough to perform the required function. ... Parallelism tolerance in gd&t is a type of orientation control tolerance. It controls the parallelism of two ... WebDec 14, 2014 · Perpendicularity is a specific form of Angularity at 90°. All of the orientation symbols (Angularity, Parallelism, and Perpendicularity) all call out the particular feature envelope referenced to a datum. The Perpendicular Symbol is also closely related to flatness when referenced/measured surface is a surface plane.
