Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATITPSCircularity
Interface to circularity (or roundness) tolerance.
Role: Objects that implement this typing interface are circularity
tolerances. This type belongs to the form super type.
It defines the capability of a circular line (and all the points constituting this line) extracted from a cylindrical surface, to entirely be within the tolerance zone. This tolerance zone is a space limited by two t-apart concentric circles. A form tolerance is specified without any reference frame.
Normative reference: ISO 1101 section 14.3 and ASME Y14.5M section 6.4.3.
