Full title and description

ISO 10303-47:1997/Cor 1:2000 — Industrial automation systems and integration — Product data representation and exchange — Part 47: Integrated generic resource: Shape variation tolerances — Technical Corrigendum 1. This corrigendum contains technical corrections to the published Part 47 (1997) text and is issued as Corrigendum 1 (2000) to clarify, correct or amend specific entries in the original edition.

Abstract

This document is a technical corrigendum to ISO 10303-47:1997 and provides corrections and clarifications to the EXPRESS schemas, definitions and normative text used to represent shape variation tolerances (dimensions, geometric tolerances, datum definitions and related constructs) within the ISO 10303 STEP integrated generic resource for tolerancing. It is intended to be applied together with the original Part 47 text.

Scope

The corrigendum corrects and clarifies specific technical items in ISO 10303-47:1997, which defines the resource constructs for representing shape dimensions and tolerances for product geometry in STEP (ISO 10303). The underlying part (Part 47) covers representation of size, relative location, datum systems, form/profile/runout tolerances and related EXPRESS schema elements; the corrigendum updates those elements where editorial or technical corrections were necessary.

Key topics and requirements

• Corrections to EXPRESS schema declarations and entity definitions used for shape-aspect, shape-dimension and shape-tolerance constructs.
• Clarifications to datum and derived-shape-aspect semantics for dimensioning and tolerancing.
• Editorial fixes to normative text that affect implementation interoperability of STEP AP resources related to tolerancing.
• Intended to be used in conjunction with the main Part 47 text (ISO 10303-47:1997) when representing tolerances in 2D and 3D product models.

Typical use and users

Engineers, CAD/CAM/CAE developers, PLM integrators and standards implementers who need to encode, exchange or archive product geometry with formal dimensioning and tolerancing semantics in STEP files. The corrigendum is primarily of interest to implementers ensuring conformance to ISO 10303-47 and to tool vendors maintaining EXPRESS schema and STEP translators.

Related standards

This corrigendum applies to and must be read alongside ISO 10303-47:1997 (Part 47). Part 47 itself references ISO 10303-1, ISO 10303-11 (EXPRESS) and related ISO drawing/tolerancing standards (for example ISO 2692, ISO 5459, ISO 10578). Part 47 was later revised (see ISO 10303-47:2014) and newer editions of the Part are available.

FAQ

Q: What is this standard?

A: It is a technical corrigendum (ISO 10303-47:1997/Cor 1:2000) that provides corrections to ISO 10303-47:1997 — the STEP integrated generic resource for shape variation tolerances.

Q: What does it cover?

A: The corrigendum fixes and clarifies parts of the EXPRESS schemas and normative text used to represent dimensions, datum definitions and geometric tolerances in Part 47 (applicable to 2D and 3D product geometry). It does not replace the main Part 47 document but amends it.

Q: Who typically uses it?

A: CAD/PLM tool developers, STEP implementers, standards experts and engineers who implement or verify STEP representations of tolerancing and related EXPRESS schemas.

Q: Is it current or superseded?

A: The corrigendum edition is withdrawn. ISO records show that the 1997 Part 47 and its corrigendum were later revised (ISO 10303-47:2014) and newer editions of Part 47 are available (ISO indicates a 2025 edition). For current implementations you should consult the latest active edition of Part 47.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 (STEP) series; Part 47 belongs to the integrated resources series within ISO 10303 and interacts with other parts such as ISO 10303-1 (overview) and ISO 10303-11 (EXPRESS).

Q: What are the key keywords?

A: Shape variation tolerances, STEP, ISO 10303, EXPRESS schema, datum, geometric tolerance, dimensioning, corrigendum.
