Full title and description

ISO 10303-503:2000/Cor 1:2006 — Industrial automation systems and integration — Product data representation and exchange — Part 503: Application interpreted construct: Geometrically bounded 2D wireframe — Technical Corrigendum 1. This corrigendum contains technical corrections and clarifications that apply to ISO 10303-503:2000 (the AIC for geometrically bounded 2D wireframe).

Abstract

This document is a Technical Corrigendum (Cor 1) to ISO 10303-503:2000. It provides corrections and clarifications to the original AIC (Application Interpreted Construct) that defines a geometrically bounded 2D wireframe representation — i.e., the constructs, types and restrictions used to represent 2D wireframe geometry as a consistent set of points and curves for STEP-based data exchange. The corrigendum is a short (5-page) corrective publication issued in December 2006.

General information

• Publication date: December 2006 (2006-12).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial automation systems and integration; product data).
• Edition / version: Edition 1 — Technical Corrigendum 1 to ISO 10303-503:2000 (Corrigendum published 2006).
• Number of pages: 5 pages.

Scope

The corrigendum applies to ISO 10303-503:2000 and is limited to correcting and clarifying the definitions, EXPRESS schema items and usage notes for the geometrically_bounded_2d_wireframe_representation AIC. The underlying purpose is to ensure consistent interpretation of the 2D wireframe constructs (points and curves) and the explicit trimming/limiting rules for unbounded curves so that STEP implementations and data exchanges remain interoperable. The 2011 revision of part 503 later consolidated these updates into the published ISO 10303-503:2011 edition.

Key topics and requirements

• Corrections to EXPRESS schema elements and identifiers used in the AIC for geometrically bounded 2D wireframe.
• Definition and use of the entity geometrically_bounded_2d_wireframe_representation (a shape_representation for 2D wireframe geometry).
• Rules for the geometric_curve_set: permitted element types (examples include b_spline_curve, circle, composite_curve, ellipse, offset_curve_2d, point, polyline, trimmed_curve) and constraints on base/segment types for offset, replica and composite curves.
• Requirement that unbounded curves must be explicitly trimmed (unless closed) and that supporting geometric objects used only for definition should not be listed as elements of the geometric_curve_set.
• Clarifications intended to improve interoperability for CAD/PLM data exchange where 2D wireframe representations are required.

Typical use and users

Typical users are implementers and integrators of STEP-based data exchange (ISO 10303) — CAD/CAM/CAE software developers, PLM/ERP integration teams, technical authors of STEP application interpreters, and standards committees verifying conformance of 2D wireframe representations. The corrigendum is primarily of interest to teams maintaining or validating EXPRESS schemas and STEP file import/export components.

Related standards

Part 503 belongs to the ISO 10303 (STEP) family of standards. Closely related and relevant documents include the integrated generic resources such as ISO 10303‑41 (fundamentals and shape_representation constructs) and other STEP parts that define geometry/topology and application-level protocols. The corrigendum was superseded by the consolidated ISO 10303-503:2011 edition, which incorporates the necessary corrections.

FAQ

Q: What is this standard?

A: This document is a Technical Corrigendum (ISO 10303-503:2000/Cor 1:2006) that corrects and clarifies the original ISO 10303-503:2000 Application Interpreted Construct for geometrically bounded 2D wireframe representations.

Q: What does it cover?

A: It covers corrections to the EXPRESS definitions, usage notes and constraints for the AIC that defines a geometrically bounded 2D wireframe representation (how points and curves are used, trimming rules for unbounded curves, and permitted curve types and their constraints). The intent is to improve consistent interpretation and interoperability for 2D wireframe data exchanged via STEP.

Q: Who typically uses it?

A: CAD/PLM software developers, data exchange and interoperability engineers, test laboratories and organizations that implement or validate STEP/AP data (especially where 2D wireframe representations are exchanged) use this corrigendum for precise implementation guidance.

Q: Is it current or superseded?

A: The corrigendum was published in December 2006 and is recorded as withdrawn; a newer consolidated edition of Part 503 (ISO 10303-503:2011) supersedes the 2000 edition and incorporates necessary updates. For current implementations refer to ISO 10303-503:2011 (and later confirmed editions).

Q: Is it part of a series?

A: Yes — it is part of the ISO 10303 (STEP) family. Part 503 is an Application Interpreted Construct (AIC) within the broader STEP structure; related parts include the integrated generic resources (for example ISO 10303‑41) and other geometry/topology application resources in the ISO 10303 series.

Q: What are the key keywords?

A: Key keywords are: ISO 10303, STEP, AP503, AIC, geometrically_bounded_2d_wireframe_representation, geometric_curve_set, EXPRESS, corrigendum, interoperability.
