4.2.363 Perpendicularity_tolerance

A Perpendicularity_tolerance is a constraint that specifies that a surface or a curve shall be perpendicular to a reference datum with an allowed amount of deviation. The reference datum is either a datum plane or a datum axis.

A Perpendicularity_tolerance specifies one of the following:

A Perpendicularity_tolerance is a type of Geometric_tolerance.

The data associated with a Perpendicularity_tolerance are the following:

4.2.363.1 affected_plane

The affected_plane specifies the plane in which the tolerance applies.

This attribute covers information that is given on drawings implicitly by the drawing plane. If the affected_plane is not specified, the tolerance applies in all directions (on drawings indicated by the diameter symbol) .

See perpendicularity_tolerance to reference_plane for the application assertion.

The affected_plane need not be specified for a particular Perpendicularity_tolerance.

4.2.363.2 reference_datum

The reference_datum specifies the Datum_reference objects that define the reference for this type of geometric tolerance.

See perpendicularity_tolerance to datum_reference for the application assertion.
