4.2.146 Derived_geometry

A Derived_geometry is the identification of a Constructive_geometric_element that is derived from an existing aspect of the shape of a part for tolerancing purposes.

The data associated with a Derived_geometry are the following:

4.2.146.1 geometry

The geometry specifies the Constructive_geometric_element that is used for tolerancing.

See derived_geometry to constructive_geometric_element for the application assertion.

4.2.146.2 is_derived_from

The is_derived_from specifies the set of Shape_element objects from which the geometric element is derived.

See derived_geometry to shape_element for the application assertion.

4.2.146.3 role

The role specifies the function of the Constructive_geometric_element when it is used as Derived_geometry.

EXAMPLE 'symmetry plane' is an example for the role.
