Application module: Part shape | ISO/TS 10303-1807:2019(E) © ISO |
This clause specifies the information requirements for the Part shape 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.
This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Part_shape_arm schema and identifies the necessary external references.
EXPRESS specification:

This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.
The part_shape_element_definition_select type is an extensible list of alternate data types that allows for the designation of the data types Shape_feature_definition and Part_shape_element.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.
