Angularity ∠
(ASME Y14.5M-1994 ,6.6.2)
(Feature Surface to Datum Surface)
The tolerance zone in this example is defined by two parallel
planes oriented at the specified angle to the datum reference plane.
Angularity is the condition of the planar feature surface at a specified angle (other than 90 degrees) to the datum reference plane, within the specified tolerance zone.
The tolerance zone in this example is defined by a cylinder equal
to the length of the feature, oriented at the specified angle to the datum reference plane.
Angularity is the condition of the feature axis at a specified angle (other than 90 degrees) to the datum reference plane, within the specified tolerance zone.
