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.
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 axis.
Angularity is the condition of the feature axis at a specified angle (other than 90 degrees) to the datum reference axis, within the specified tolerance zone.
Perpendicularity ⊥
(ASME Y14.5M-1994 ,6.6.4)
(Feature Surface to Datum Surface)
The tolerance zone in this example is defined by two parallel
planes oriented perpendicular to the datum reference plane.
Perpendicularity is the condition of the planar feature surface at a right angle to the datum reference plane, within the specified tolerance zone.

Parallelism ⁄ ⁄
(ASME Y14.5M-1994 ,6.6.3)
(Feature Surface to Datum Surface)
The tolerance zone in this example is defined by two
parallel planes oriented parallel to the datum reference plane.
Parallelism is the condition of the planar feature surface equidistant at all points from the datum reference plane, within the specified tolerance zone.
The tolerance zone in this example is defined by
two parallel planes oriented parallel to the datum reference plane.
Parallelism is the condition of the feature axis equidistant along its length from 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 parallel to the datum reference axis.
Parallelism is the condition of the feature axis equidistant along its length from the datum reference axis, within the specified tolerance zone.
