ISO 10303-214:2010(E)
A Constructive_geometry is a collection of non-shape geometry that is used to support the definition of a Geometric_model. Each Constructive_geometry shall refer directly or indirectly, via intermediate Constructive_geometry objects, to a Geometric_model through Constructive_geometry_association objects.
The data associated with a Constructive_geometry are the following:
The element specifies the Constructive_geometric_element objects the Constructive_geometry consists of.
See constructive_geometry to constructive_geometric_element for the application assertion.
The name specifies the word or group of words by which the Constructive_geometry is referred to.
See constructive_geometry to multi_language_string for the application assertion.
The name need not be specified for a particular Constructive_geometry.
If present, there shall be exactly one object that defines the name for a Constructive_geometry.
