5.2 MIM EXPRESS short listing

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:

• use of a supertype entity does not make applicable any of its specializations, unless the specialization is also imported in the MIM schema;
• use of a SELECT type does not make applicable any of its listed types unless the listed type is also imported in the MIM schema.

USE FROM Basic_geometry_mim;    --  ISO/TS 10303-1652



USE FROM External_item_identification_assignment_mim;    --  ISO/TS 10303-1128



USE FROM geometry_schema    --  ISO 10303-42
  (circle,
   trimmed_curve,
   line,
   composite_curve,
   composite_curve_segment,
   pcurve,
   surface_curve);

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

Basic_geometry_mim	ISO/TS 10303-1652
External_item_identification_assignment_mim	ISO/TS 10303-1128
geometry_schema	ISO 10303-42

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

5.2.1 MIM type definition

This subclause specifies the MIM type for this application module. The MIM type and definition is specified below.

5.2.1.1 bc_external_identification_item   

The bc_external_identification_item type is an extension of the external_identification_item type. It adds the data type trimmed_curve 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 bc_external_identification_item = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON external_identification_item WITH
   (trimmed_curve);
END_TYPE;
