Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1659: Application module: Curve swept solid. This technical specification defines an ISO/STEP application module for representing curve‑swept solids (extruded solids along a curve with a fixed cross‑section and orientation) for product data exchange.

Abstract

ISO/TS 10303-1659:2006 specifies the application module for a curve swept solid. It covers the definition of an extruded solid created by sweeping a fixed cross‑section along a B‑spline (or similar) centreline with orientation, and references items within the scope of the elemental geometric shape application module. The module is intended for use within the STEP (ISO 10303) modular framework to support interoperable exchange of this geometric construct.

Scope

The scope of ISO/TS 10303-1659:2006 is to define an application module within the ISO 10303 (STEP) series that represents curve‑swept solids: solids generated by sweeping a fixed cross‑section along a parametric centreline (for example a B‑spline curve) with defined orientation. The module includes the necessary data constructs and semantics to describe geometry, placement and orientation of the cross‑section along the path and relies on related elemental geometric shape modules for base types and primitives.

Key topics and requirements

• Definition of the curve‑swept solid (extrusion along a curve acting as centreline).
• Support for B‑spline or parametric centreline definitions and orientation control along the sweep.
• Fixed cross‑section specification and placement/orientation semantics.
• Express schema constructs suitable for STEP application module implementation.
• Dependencies and interoperability with elemental geometric shape modules (e.g., ISO/TS 10303‑1004 and other STEP resources).
• Requirements to support reliable data exchange between CAD/CAM/PDM tools that implement STEP modules.

Typical use and users

Implementers of STEP translators, CAD/CAM/PDM software developers, systems integrators and organizations exchanging product geometric data use this module when models include solids produced by sweeping a cross‑section along a curve (for example pipes, ducts, swept structural members, or specialized extrusions following complex paths). Researchers and standards engineers working on geometric interoperability and STEP application protocols also refer to this module. For context on how application modules fit into the STEP family and typical users, see general STEP overviews.

Related standards

ISO/TS 10303-1659 is part of the ISO 10303 (STEP) family and is intended to be used alongside other STEP application modules and resource parts (for example elemental geometric shape modules and common resource schemas). It specifically references items within the scope of the elemental geometric shape application module (ISO/TS 10303‑1004) and operates within the modular AP/resource architecture of ISO 10303. More broadly, implementers will consider related APs and resource parts within ISO 10303 when integrating this module into translators and data models.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1659:2006 is a STEP technical specification (an application module) that defines how to represent curve‑swept solids for product data exchange within the ISO 10303 framework.

Q: What does it cover?

A: It covers the data constructs and semantics needed to describe an extruded solid generated by sweeping a fixed cross‑section along a parametric curve (such as a B‑spline), including orientation along the path and links to elemental geometric types.

Q: Who typically uses it?

A: CAD/CAM/PDM software developers, STEP translator implementers, systems integrators, and standards engineers who need to exchange or archive geometry defined as curve‑swept solids.

Q: Is it current or superseded?

A: The document was published in December 2006 (Edition 1). According to the ISO record, this Technical Specification was reviewed and confirmed in 2023 and remains the current published version at the time of that confirmation. Users should check ISO records or national standards bodies for any later revisions or withdrawal notices.

Q: Is it part of a series?

A: Yes — it is one part (part 1659) of the ISO 10303 family (STEP), which is a modular series of parts—application protocols, application modules and resources—covering many geometry types and product data constructs.

Q: What are the key keywords?

A: Curve swept solid; swept extrusion; B‑spline centreline; application module; STEP; ISO 10303; geometric representation; product data exchange.
