Join Kipp Bradford for an in-depth discussion in this video Basic GD&T symbols: Orientation, part of Geometric Dimensioning and Tolerancing.
- [Instructor] Orientation tolerances control…the angle of a given feature relative to a given datum.…Two special cases of angle features exist.…When the desired angle is either zero…and the feature is parallel to the datum,…or 90 degrees and the feature is perpendicular to the datum.…The perpendicularity control constrains how far…an axis or a plane can deviate from a right angle…with regards to a datum reference plane or a line.…Perpendicularity is defined as a distance, not as an angle.…
So it describes the set of parallel lines or planes…perpendicular to the datum, which lie on either side…of the geometry being controlled.…These lines or planes are separated by…a distance specified by the perpendicularity control.…Every point of the geometry being controlled…must lie between these parallel lines or planes.…The parallelism control constrains how far…an axis or a plane can deviate from parallel…with regards to a datum reference plane or line.…Parallelism is defined as a distance,…so it describes the set of parallel lines…
