Application module: Dimension tolerance | ISO/TS 10303-1050:2019(E) © ISO |
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:
Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

This subclause specifies the MIM types for this application module. The MIM types and definitions are specified below.
The dimension_identification_item type is an extension of the identification_item type. It adds the data type dimensional_size to the list of alternate data types.
EXPRESS specification:
*)
TYPE
dimension_identification_item =
SELECT
BASED_ON
identification_item
WITH
(dimensional_size);
END_TYPE;
(*
The dimension_tolerance_document_reference_item type is an extension of the document_reference_item type. It adds the data types dimensional_size and externally_defined_dimension_definition to the list of alternate data types.
EXPRESS specification:
*)
TYPE
dimension_tolerance_document_reference_item =
SELECT
BASED_ON
document_reference_item
WITH
(dimensional_size,
externally_defined_dimension_definition);
END_TYPE;
(*
The dt_action_items type is an extension of the action_items type. It adds the data types dimensional_location, dimensional_size, and directed_dimensional_location to the list of alternate data types.
EXPRESS specification:
*)
TYPE
dt_action_items =
SELECT
BASED_ON
action_items
WITH
(dimensional_location,
dimensional_size,
directed_dimensional_location);
END_TYPE;
(*
This subclause specifies the MIM entity for this module. The MIM entity and definition is specified below.
EXPRESS specification:
*)
ENTITY externally_defined_dimension_definition
SUBTYPE OF (dimensional_size, externally_defined_item);
WHERE
WR1: (SELF\externally_defined_item.item_id = 'external size dimension') AND (SELF\externally_defined_item.source.source_id

END_ENTITY;
(*
Formal propositions:
WR1: The item_id shall be 'external size dimension' and the source attribute shall reference an external_source with a source_id of 'externally defined dimension specification'.
WR2: The externally_defined_dimension_definition shall be referenced by the items attribute of type applied_document_reference that references through the assigned_document attribute a document with description of 'externally defined dimension specification'.
