RECTIFICATIF TECHNIQUE 1
Technical Corrigendum 1 to International Standard ISO 10303-46:1994 was prepared by Technical Committee
ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 4, Industrial data.
Introduction
This document corrects ISO 10303-46:1994, Product data representation and exchange — Part 46:
Integrated generic resources: Visual presentation. The corrected document supersedes ISO
10303-46:1994.
The purpose of the modifications to the text of ISO 10303-46:1994 is to correct errors in the EXPRESS
definitions likely to cause a compilation problem, to correct errors in Informal propositions and
Formal propositions, to replace the annex for the computer-interpretable EXPRESS with a URL
reference, and to replace the object identifier for the document and the schemas.

Modifications to the text of ISO 10303-46:1994
Clause 4, p. 5
The EXPRESS specification for the presentation_organization_schema did not include a reference to
required data type. The first required data type is an entity data type, the annotation_occurrence for
the Formal propositions in area_dependent_annotation_representation and view_dependent_
annotation_representation. The second required data type is an entity data type, the symbol_
representation for the Formal propositions in symbol_representation_rule. The third required data
type is an entity data type, the symbol_representation_relationship for the Formal propositions in
symbol_representation_rule. The fourth required data type is an entity data type, the styled_item for
the Formal propositions in camera_model and light_source. The fifth required data type is an entity
data type, the founded_item. It is required to be referenced since it is now a supertype of
view_volume. Add the following to the EXPRESS specification between the 'SCHEMA
presentation_organization_schema;' and the 'REFERENCE FROM presentation_resource_schema':
REFERENCE FROM presentation_definition_schema
(annotation_occurrence,
symbol_representation,
symbol_representation_relationship);
REFERENCE FROM presentation_appearance_schema
(styled_item);
Delete the following EXPRESS specification:
REFERENCE FROM representation_schema
(item_defined_transformation,
item_in_context,
mapped_item,
representation,
representation_item,
representation_map,
representation_relationship,
representation_relationship_with_transformation);
Replace with the following EXPRESS specification:
REFERENCE FROM representation_schema
(founded_item,
item_defined_transformation,
item_in_context,
mapped_item,
representation,
representation_item,
representation_map,
ISO 10303-46:1994/Cor.1:1999(E) ©ISO
representation_relationship,
representation_relationship_with_transformation);
With the addition of the annotation_occurrence, symbol_representation, symbol_representation_
relationship and styled_item to the presentation_organization_schema, NOTE 1 changed. Delete
NOTE 1 and replace with the following:
NOTE 1  The schemas referenced above can be found in the following parts of ISO 10303:
Presentation_definition_schema Clause 5 of this part of ISO 10303
Presentation_appearance_schema Clause 6 of this part of ISO 10303
Presentation_resource_schema Clause 7 of this part of ISO 10303
Geometry_schema ISO 10303-42
Representation_schema ISO 10303-43
Measure_schema ISO 10303-41
Support_resource_schema ISO 10303-41
Clause 4.3.45, p. 13
The Informal proposition of layered_item contradicts to the intended use of presentation_layer_
assignment. The type of representation_items assigned to a layer shall not be restricted. Remove
Informal proposition IP1.
Clause 4.5.5, p. 26
The EXPRESS specification of view_volume is revised to make it a subtype of founded_item in order
to provide a representation context for the projection_point and planar_box attributes. Remove the
EXPRESS specification and replace with the following:
EXPRESS specification:
*)
ENTITY view_volume
SUBTYPE OF (founded_item);
projection_type      : central_or_parallel;
projection_point      : cartesian_point;
view_plane_distance    : length_measure;
front_plane_distance    : length_measure;
front_plane_clipping    : BOOLEAN;
back_plane_distance    : length_measure;
back_plane_clipping    : BOOLEAN;
view_volume_sides_clipping : BOOLEAN;
view_window        : planar_box;
END_ENTITY;
(*
Add the following note at the end of the entity description:
©ISO ISO 10303-46:1994/Cor.1:1999(E)
NOTE  Since view_volume is not a subtype of geometric_representation_item the instances of
cartesian_point which is the projection_point attribute and planar_box which is the view_window attribute
are not associated in the usual way with the geometric_representation_context of each representation using a
camera_model_d3 containing this view_volume. The geometric_representation_context is associated via
the supertype.
founded_item
Clause 4.5.9, p. 31
The EXPRESS specification of light_source contained logical errors in the WHERE rule. WR1
requires a role name qualified by attribute name 'ITEM' for argument 2 of built-in function USEDIN.
Delete the current WR1 and replace WR1 with the following:
WR1: SIZEOF(USEDIN(SELF,'PRESENTATION_APPEARANCE_SCHEMA.'+
'STYLED_ITEM.ITEM')) = 0;
Clause 4.5.14, p. 35
The description of the Formal propositions does not give a correct explanation of WR2. Remove the
description of WR2 and replace with the following:
WR2: The target of the mapping shall be a planar_box.
Clause 4.9.1, p. 39
The EXPRESS specification for the FUNCTION acyclic_presentation_representation_relationship
contained logical errors in the function body. The assignment to variable 'x' requires a ‘SET' and not
a 'BAG'. Remove the EXPRESS specification and replace with the following:
EXPRESS specification:
*)
FUNCTION acyclic_presentation_representation_relationship
( relation : presentation_representation_relationship;
children : SET OF presentation_representation ) : BOOLEAN;
LOCAL
x : SET OF presentation_representation_relationship;
local_children : SET OF presentation_representation;
END_LOCAL;
REPEAT i:=1 TO HIINDEX(children);
IF relation\representation_relationship.rep_1 :=: children[i] THEN
RETURN(FALSE);
END_IF;
END_REPEAT;
x := bag_to_set (USEDIN ( relation\representation_relationship.rep_1,
'REPRESENTATION_SCHEMA.'+
'REPRESENTATION_RELATIONSHIP.REP_2'));

END_FUNCTION;
(*
Clause 5, p. 40
The EXPRESS specification for the presentation_definition_schema did not include a reference to a
required data type. The required reference is a function, the bag_to_set for the EXPRESS
specifications changed in acyclic_presentation_representation_relationship, acyclic_symbol_
representation_relationship and field_in_table. Delete the following EXPRESS specification:
REFERENCE FROM support_resource_schema
(label,
text);
Replace with the following EXPRESS specification:
REFERENCE FROM support_resource_schema
(label,
text,
bag_to_set);
Clause 5.4.13, p. 53
The EXPRESS specification of table_record_representation contained logical errors in the WHERE
rule. WR1 requires 'REPRESENTATION_SCHEMA.REPRESENTATION_MAP' as argument 2 of built-
in function USEDIN and not 'REPRESENTATION_SCHEMA.MAPPED_ITEM.MAPPING_
SOURCE.MAPPED_REPRESENTATION'. Delete the current WR1 and replace WR1 with the
following:
WR1: (SIZEOF(USEDIN(SELF, 'REPRESENTATION_SCHEMA.'+
'REPRESENTATION_RELATIONSHIP.REP_2')) > 0)
OR
(SIZEOF( QUERY( map_item <* USEDIN(SELF, 'REPRESENTATION_SCHEMA.'+

'PRESENTATION_DEFINITION_SCHEMA.TABLE_REPRESENTATION' IN
TYPEOF (using_representations (map_item)) )) > 0);
Clause 5.4.14, p. 54
The EXPRESS specification of table_record_field_representation contained logical errors in the
WHERE rule. WR1 requires 'REPRESENTATION_SCHEMA.REPRESENTATION_MAP' as argument 2
of built-in function USEDIN and not 'REPRESENTATION_SCHEMA.MAPPED_ITEM.MAPPING_
SOURCE.MAPPED_REPRESENTATION'. Delete the current WR1 and replace WR1 with the
following:
WR1: (SIZEOF(USEDIN(SELF, 'REPRESENTATION_SCHEMA.' +
'REPRESENTATION_RELATIONSHIP.REP_2')) > 0)
OR
(SIZEOF( QUERY( map_item <* USEDIN(SELF, 'REPRESENTATION_SCHEMA.'+

'TABLE_RECORD_REPRESENTATION' IN
TYPEOF (using_representations (map_item)) )) > 0);
Clause 5.6.2, p. 72
The EXPRESS specification for the FUNCTION acyclic_symbol_representation_relationship
contained logical errors in the function body. The assignment to variable 'x' requires a ‘SET' and not
a 'BAG'. Remove the EXPRESS specification and replace with the following:
EXPRESS specification:

Clause 5.6.3, p. 73
The EXPRESS specification for the FUNCTION field_in_table contained spelling and logical errors.
The expression in the first QUERY requires a string 'PRESENTATION_DEFINITION_SCHEMA.
TABLE_RECORD_REPRESENTATION' and not a string 'PRESENTATION_DEFINITIONS_
SCHEMA.TABLE_RECORD_REPRESENTATION'. The declaration of variable 'symbol_rep_rel_set'
