Full title and description

St ISO TS 10303-1514-2008 — Industrial automation systems and integration — Product data representation and exchange — Part 1514: Application module: Advanced boundary representation. This technical specification defines the application module (ARM) for advanced boundary representation within the ISO 10303 (STEP) family, covering EXPRESS definitions and mappings for B-rep and related geometric concepts.

Abstract

Specifies the application module for Advanced boundary representation (B-reps). The module captures 3D geometry and related constructs such as B-reps, B-rep models, B‑spline curves and surfaces, conics, elementary curves/surfaces, geometric transformations, polylines, pcurves, sculptured and swept surfaces, twisted curves, unbounded geometry and use of topology to bound geometric entities.

General information

• Status: Withdrawn (stage: withdrawal of international standard).
• Publication date: December 2008.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control / product data representation and exchange).
• Edition / version: Edition 2 (ISO/TS 10303-1514:2008).
• Number of pages: 44 pages.

Scope

Defines the information requirements, ARM entity definitions and mappings required to represent advanced boundary representation information in STEP-based data exchange. The module addresses 3D boundary representations, parametric and non-parametric curves and surfaces, topology used to bound geometry, and interoperability with related STEP modules (for example topologically bounded surfaces and faceted B-reps). It is intended to be used as a reusable application module within ISO 10303 application protocols and module libraries.

Key topics and requirements

• Representation of 3D geometry and B-reps (boundary representation models).
• Support for B‑spline curves and surfaces, conics and other elementary curve/surface types.
• Definitions for geometric transformations and coordinate/parameter (pcurve) relationships.
• Support for sculptured, swept and twisted curve/surface constructs and unbounded geometry.
• Use of topology to bound geometric entities and interactions with faceted and topologically bounded-surface modules.
• EXPRESS ARM definitions, mapping to MIM, and computer-interpretable listings (for implementers).

Typical use and users

Used by CAD/CAM/CAE vendors, product data management (PDM/PLM) system developers, implementers of STEP APs and application modules, systems integrators, and organizations exchanging complex 3D boundary-representation geometry between systems. Also relevant to standards engineers and researchers who develop or map EXPRESS schemas and MIM/ARM mappings.

Related standards

Part of the ISO 10303 (STEP) family. Close related modules include ISO/TS 10303-1511 (Topologically bounded surface), ISO/TS 10303-1512 (Faceted boundary representation) and modules addressing solid models and other geometry (for example ISO/TS 10303-1793 in later revisions). The module is intended to interoperate with other ISO 10303 application modules and the STEP Module and Resource Library (SMRL).

FAQ

Q: What is this standard?

A: ISO/TS 10303-1514:2008 (listed here as St ISO TS 10303-1514-2008) is a STEP technical specification that defines the Advanced boundary representation application module (ARM) for representing B‑rep geometry and related constructs in ISO 10303 exchanges.

Q: What does it cover?

A: It covers EXPRESS ARM definitions, information requirements, MIM mappings and computer-interpretable listings for advanced B‑rep geometry: B‑reps, B‑spline curves/surfaces, conics, elementary geometry, geometric transformations, pcurves, sculptured/swept surfaces, and topology used to bound geometry.

Q: Who typically uses it?

A: CAD/CAM/CAE vendors, PLM/PDM implementers, data exchange/integration engineers, and standards implementers who require a reusable module for exchanging complex boundary-representation geometry in STEP-based workflows.

Q: Is it current or superseded?

A: The 2008 edition is withdrawn. ISO subsequently published revised editions (a 2010 edition and later revisions); more recent published activity for this part includes 2010 and 2018 editions (both shown as withdrawn in ISO records) and a published version in 2024 (edition 5, published September 2024). For current implementations you should consider the latest published edition (2024).

Q: Is it part of a series?

A: Yes — it is Part 1514 of ISO 10303 (the STEP family). ISO 10303 is a modular standard composed of multiple parts (application protocols, application modules and resources) covering product data representation and exchange.

Q: What are the key keywords?

A: Advanced boundary representation, B-rep, B-spline, pcurve, sculptured surface, swept surface, topology, STEP, ISO 10303, EXPRESS ARM.
