Surface perpendicularity is a 2-dimensional GD&T callout that controls the perpendicularity between two surfaces. It can control the perpendicularity of a surface or an axis.
Similar to GD&T straightness, there are two ways in which perpendicularity may be applied.
The perpendicularity callout establishes limits within which a feature must lie to be accepted as reasonably perpendicular. VII Bonus Tolerance in Perpendicularity What Is Perpendicularity?Įxact perpendicularity between features is very difficult to achieve.
