Angularity is the condition of a feature which is at any any angle other than parallel or perpendicular to a datum. The tolerance zone will be a width between parallel planes or line. A cylindrical tolerance zone is not applicable. The dimension defining the angle between the datum and controlled feature must be basic and must be placed between the feature and datum.
When the angularity of a surface is controlled relative to a datum plane, the tolerance zone is confined be two planes that are at a specified angle to the datum plane.
