ISO 10303-214:2010(E)
A Geometric_model_relationship is a relationship between two models. The models may be either of type Geometric_model or of type External_model.
Each Geometric_model_relationship may be a Geometric_model_relationship_with_transformation.
The data associated with a Geometric_model_relationship are the following:
The description specifies additional information about the Geometric_model_relationship.
See geometric_model_relationship to multi_language_string for the application assertion.
The description need not be specified for a particular Geometric_model_relationship.
If present, there shall be exactly one object that defines the description for a Geometric_model_relationship.
The related specifies the second of the two model objects related by the Geometric_model_relationship.
NOTE The semantics of this attribute are defined by the attribute relation_type.
See geometric_model_relationship to external_model and geometric_model_relationship to geometric_model for the application assertions.
There shall be exactly one object that the Geometric_model_relationship is related to.
The relating specifies the first of the two model objects related by the Geometric_model_relationship.
NOTE The semantics of this attribute are defined by the attribute relation_type.
See geometric_model_relationship to external_model and geometric_model_relationship to geometric_model for the application assertions.
There shall be exactly one object that the Geometric_model_relationship is relating to.
The relation_type specifies the meaning of the relationship.
EXAMPLE The relation_type may be, e.g., 'basis for' if the relating Geometric_model provides a detailed representation of the shape of an object and if the related Geometric_model provides an idealized representation of the shape of the same object.
