Application module: Extended basic geometry | ISO/TS 10303-1667:2014-02(E) © ISO |
This clause specifies the EXPRESS schema derived from the mapping table. It uses elements from the common resources or from other application modules and defines the EXPRESS constructs that are specific to this part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the application module.
This clause also specifies the modifications that apply to the constructs imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application modules:

Attribute definitions:
relating_representation_item: an attribute inherited from the representation_item_relationship shall be redeclared as the geometric_representation_item for the geometric_model_element_relationship.
related_representation_item: an attribute inherited from the representation_item_relationship shall be redeclared as the geometric_representation_item for the geometric_model_element_relationship.
Formal propositions:
UR1: The combination of relating_representation_item and related_representation_item shall be unique within a population of geometric_model_element_relationship.
WR1: The relating_representation_item shall not be related_representation_item.
