Technical Corrigendum1 to International Standard ISO 10303-101:1994 was prepared by Technical Committee
ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 4, Industrial data.
Introduction
This document corrects ISO 10303-101:1994, Product data representation and exchange — Part 101: Integrated
application resources: Draughting. The corrected document supersedes ISO 10303-101:1994.
The purpose of the modifications to the text of ISO 10303-101:1994 is to correct errors in the EXPRESS definitions
likely to cause compilation problems, to replace the annex for the computer-interpretable EXPRESS with a URL
reference, and to replace the object identifiers for the document and the schema.

Modifications to the text of ISO 10303-101:1994
Clause 4.4.6, p. 9
The EXPRESS specification of drawing_sheet_revision_usage contained logical errors in the WHERE rules.
requires additional sets of parentheses for proper evaluation.  Delete WR1 and replace WR1 with the following:
 WR1: ('DRAWING_DEFINITION_SCHEMA.DRAWING_SHEET_REVISION' IN
        TYPEOF(SELF\area_in_set.area))
    AND
    ('DRAWING_DEFINITION_SCHEMA.DRAWING_REVISION'
     IN TYPEOF(SELF\area_in_set.in_set));
Clause 5.4.1, p. 15
The EXPRESS specification and the Formal proposition of dimension_curve contained errors in the WHERE rules.
Delete the EXPRESS specification for dimension_curve and replace with the following:
:
