4 Information requirements

This clause specifies the information requirements for the Compound shape representation application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.

NOTE 1  A graphical representation of the information requirements is given in Annex C.

NOTE 2  The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.

The following EXPRESS specification begins the Compound_shape_representation_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Compound_shape_representation_arm;

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM Edge_based_wireframe_arm;    --  ISO/TS 10303-1501

USE FROM Non_manifold_surface_arm;    --  ISO/TS 10303-1324
(*

NOTE 1   The schemas referenced above are specified in the following part of ISO 10303:

Edge_based_wireframe_arm ISO/TS 10303-1501
Non_manifold_surface_arm ISO/TS 10303-1324

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM entity definition

This subclause specifies the ARM entity for this module. The ARM entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entity and definition is specified below.

4.2.1 Compound_shape_representation   EXPRESS-GMapping table

A Compound_shape_representation is a type of Geometric_model. A Compound_shape_representation is a geometry model where elements of different dimensionality, such as wireframe models or surface models, are topologically connected. The topology of a Compound_shape_representation may be non-manifold.

NOTE    A Compound_shape_representation may include non-manifold surface models as well as topologically bounded three-dimensional wireframe models.
