4 Information requirements

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:

*)
SCHEMA Stratum_non_planar_shape_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 Layered_interconnect_module_design_arm;    --  ISO/TS 10303-1698

USE FROM Manifold_surface_arm;    --  ISO/TS 10303-1509
(*

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

Layered_interconnect_module_design_arm ISO/TS 10303-1698
Manifold_surface_arm ISO/TS 10303-1509

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

4.2 ARM type definitions

This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.

4.2.1 snps_sf_shape_select   EXPRESS-G

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.

EXPRESS specification:

*)
TYPE snps_sf_shape_select = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON limd_sf_shape_select WITH
   (Shell_based_surface_model);
END_TYPE;
(*

4.2.2 snps_stratum_shape_model_select   EXPRESS-G

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.

NOTE  The list of entity data types may be extended in application modules that use the constructs of this module.

EXPRESS specification:

*)
TYPE snps_stratum_shape_model_select = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON limd_stratum_shape_model_select WITH
   (Stratum_average_surface_shape_model,
    Stratum_surface_shape_model);
END_TYPE;
(*

4.3 ARM entity definitions

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

4.3.1 Stratum_average_surface_shape_model   EXPRESS-GMapping table

A Stratum_average_surface_shape_model is a type of Topologically_constrained_manifold_surface_shape_representation. A Stratum_average_surface_shape_model is the representation of a Stratum_average_surface using an open manifold surface.

EXPRESS specification:

*)
ENTITY Stratum_average_surface_shape_model
  SUBTYPE OF (Topologically_constrained_manifold_surface_shape_representation);
  of_surface : Stratum_average_surface;
UNIQUE
  UR1: of_surface;
WHERE
  WR1: NOT EXISTS(SELF\Representation.name);
  WR2: NOT EXISTS(SELF\Representation.description);
END_ENTITY;
(*

Attribute definitions:

of_surface: specifies a role of a Stratum_average_surface for the Stratum_average_surface_shape_model.

Formal propositions:

UR1: The of_surface shall be unique within a population of the Stratum_average_surface_shape_models.

WR1: The name shall not be populated.

WR2: The description shall not be populated.

4.3.2 Stratum_surface_shape_model   EXPRESS-GMapping table

A Stratum_surface_shape_model is a type of Topologically_constrained_manifold_surface_shape_representation. A Stratum_surface_shape_model is the representation of a Stratum_surface using an open manifold surface.

EXPRESS specification:

  SUBTYPE OF (Topologically_constrained_manifold_surface_shape_representation);
  of_surface : Stratum_surface;
UNIQUE
  UR1: of_surface;
WHERE
  WR1: NOT EXISTS(SELF\Representation.name);
  WR2: NOT EXISTS(SELF\Representation.description);
END_ENTITY;
(*

Attribute definitions:

of_surface: specifies a role of a Stratum_surface for the Stratum_surface_shape_model.

Formal propositions:

UR1: The of_surface shall be unique within a population of the Stratum_surface_shape_models.

WR1: The name shall not be populated.

WR2: The description shall not be populated.

4.3.3 Topologically_constrained_manifold_surface_shape_representation   EXPRESS-GMapping table

A Topologically_constrained_manifold_surface_shape_representation is a type of Manifold_surface_shape_representation that shall neither self-intersect nor self-overlap.

EXPRESS specification:

*)
ENTITY Topologically_constrained_manifold_surface_shape_representation
  SUBTYPE OF (Manifold_surface_shape_representation);
END_ENTITY;
(*

Informal propositions:

IP1: The Shell_based_surface_model that are contained in this representation shall not intersect.

IP2: The Shell_based_surface_model that are contained in this representation shall not overlap.
