Application module: Compound shape representation | ISO/TS 10303-1327:2010-03(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:

Formal propositions:
WR1: The compound_shape_representation shall have a coordinate_space_dimension equal to three.
WR2: The items in the compound_shape_representation shall be of type edge_based_wireframe_model, face_based_surface_model, mapped_item or axis2_placement_3d.
WR3: The items of a compound_shape_representation shall include at least one mapped_item or one edge_based_wireframe_model or one face_based_surface_model.
WR4: If there is a mapped_item in a compound_shape_representation, the source of the mapped_item shall be a compound_shape_representation, a edge_based_wireframe_shape_representation, or a non_manifold_surface_shape_representation.
Informal propositions:
IP1: All elements in a compound_shape_representation shall be topologically connected.
