4.2.99 Concentricity_tolerance
A Concentricity_tolerance is a constraint defining one of the following two conditions:
- a condition where the axes of all cross-sectional elements of a surface of revolution perpendicular to the axis of a datum feature are common to this axis. In this case, it implies a cylindrical tolerance zone whose axis coincides with the datum axis and within which all cross-sectional axes of the feature being controlled must lie;
- a condition where the centre point of one sphere is common to the centre point of another sphere. In this case, it implies a spherical tolerance zone within which the centre point of the first sphere must lie.
A Concentricity_tolerance is a type of Geometric_tolerance.
The data associated with a Concentricity_tolerance are the following:
reference_datum
The reference_datum specifies the Datum_reference objects that define the reference for this type of geometric tolerance.
See concentricity_tolerance to datum_reference for the application assertion.
