Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 515: Application interpreted construct: Constructive solid geometry (ISO 10303-515:2000). This part of the ISO 10303 (STEP) family defines the application‑interpreted constructs used to represent constructive solid geometry (CSG) models for product data exchange.

Abstract

ISO 10303-515:2000 specifies constructs for representing constructive solid geometry within the STEP framework. It defines the use of integrated resources and the necessary entity constructs to describe solid primitives and boolean operations (union, intersection, difference) so that CSG models can be exchanged between CAD/PLM systems. The 2000 edition has since been withdrawn and a revised version was published in 2019 that consolidates and updates the resource constructs for CSG.

Scope

This part of ISO 10303 defines an application‑interpreted construct (AIC) for Constructive Solid Geometry (CSG). Its scope covers the definition and interpretation of integrated resource constructs necessary to represent CSG models built from solid primitives and the boolean operations that combine them; it is intended to be used within STEP application protocols and by implementers exchanging CSG‑based geometry. The 2000 edition provided the initial AIC; the AIC and resource usage were reviewed and reissued in a consolidated 2019 edition.

Key topics and requirements

• Definition of CSG primitives and parameterization (primitives used as building blocks for solids).
• Specification of boolean operations: union, intersection and difference, and their representation in STEP.
• Integration and use of ISO 10303 integrated resources (IRs) to ensure consistent geometry and topology referencing.
• Entity and attribute definitions required for exchanging CSG models between systems.
• Conformance considerations for implementers exchanging CSG data within APs or AIC frameworks.

Typical use and users

Primary users are CAD and CAM software developers, PLM integrators, systems implementing STEP application protocols or modules, data exchange and archival specialists, and advanced manufacturing tool vendors that need to import/export CSG representations. Researchers and toolsmiths working on geometric kernels and interoperability testing also use this AIC.

Related standards

ISO 10303 is a modular family (STEP); related and commonly referenced parts include implementation and resource parts such as ISO 10303-21 (STEP-file encoding), numerous integrated resource parts and application protocols (APs) for mechanical design (for example AP203/AP214/AP242), and neighboring AICs such as ISO 10303-511 (Application interpreted construct: Topologically bounded surface). Implementers typically use ISO 10303-515 together with the relevant IRs and APs for complete exchange scenarios.

FAQ

Q: What is this standard?

A: ISO 10303-515:2000 is Part 515 of the ISO 10303 family (STEP) that defines an application‑interpreted construct for constructive solid geometry, specifying how CSG models are represented for product data exchange.

Q: What does it cover?

A: It covers the entity constructs and use of integrated resources needed to represent solid primitives and boolean combinations (union, intersection, difference) so that CSG models can be exchanged between systems using STEP. The 2000 edition provided the original AIC; the AIC and resource usage were later revised in a 2019 edition.

Q: Who typically uses it?

A: CAD/CAM/CAE software developers, PLM and systems integrators, implementers of STEP APs/modules, and organizations needing reliable interchange or archival of CSG geometry.

Q: Is it current or superseded?

A: The 2000 edition has been withdrawn and superseded by ISO 10303-515:2019 (published November 2019). Users should consult the 2019 edition for the current, maintained specification.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 (STEP) family of standards for product data representation and exchange. The family includes parts for data description (EXPRESS), implementation methods (STEP-file, SDAI), integrated resources (IRs), application protocols (APs) and other AICs and modules.

Q: What are the key keywords?

A: CSG, STEP, ISO 10303, AIC, integrated resources, boolean operations, product data exchange, CAD interoperability.
