Application module: Stratum non planar shape | ISO/TS 10303-1748:2021(E) © ISO |
This clause specifies the information requirements for the Stratum non planar 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 Stratum_non_planar_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 snps_sf_shape_select type is an extension of the limd_sf_shape_select type. It adds the data type Shell_based_surface_model to the list of alternate data types.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.

The snps_stratum_shape_model_select type is an extension of the limd_stratum_shape_model_select type. It adds the data types Stratum_average_surface_shape_model and Stratum_surface_shape_model to the list of alternate data types.
