Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 111: Integrated application resource: Elements for the procedural modelling of solid shapes. This part of ISO 10303 (STEP) defines resource entities and constructs to represent shape elements and feature-based (procedural / construction-history) modelling operations used in modern CAD systems, enabling exchange and reconstruction of solid models with their construction history preserved.

Abstract

ISO 10303-111:2007 provides an integrated application resource that represents shape elements and procedural modelling constructs (feature definitions and operations) so that solid models created in CAD systems can be exchanged or reconstructed with their construction history.

General information

• Status: Published (International Standard; confirmed in ISO systematic review process).
• Publication date: May 2007 (Edition 1 — commonly listed as 15 May 2007).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial automation systems and integration — Product data representation and exchange).
• Edition / version: Edition 1 (2007).
• Number of pages: 95.

Scope

Defines an integrated generic resource of STEP (ISO 10303) that specifies entities, attributes and relationships for procedural modelling of solid shapes. The scope covers representation of feature-based modelling elements (for example extrusions, revolutions, sweeps, blends, chamfers, holes, patterns and similar construction-history items), their parameterisation and interrelations so that CAD models can be exchanged retaining sufficient information to reproduce or edit the model’s construction history.

Key topics and requirements

• Representation of procedural (construction-history / feature-based) modelling elements for solids (entities for common features and operations).
• Definitions of parameters, references and constraints needed to reconstruct feature operations and their sequencing.
• EXPRESS schema constructs and data types to express the resource as part of the STEP modular framework.
• Integration with other STEP resources and application protocols (mapping to generic resources such as geometry, topology and mathematical constructs).
• Conformance guidance: use of the resource within STEP application protocols, and applicability in data exchange and PLM workflows.
• Document corrigenda and technical corrections issued after publication (see Corr.1 2008 and Corr.2 2014).

Typical use and users

Used by CAD and PLM software vendors, data-exchange/tooling developers, systems integrators, manufacturing engineering teams and researchers who need to exchange, reconstruct or reuse CAD models with construction history preserved. Typical applications include CAD interoperability, model translation services, model-based engineering workflows, and advanced model validation and feature recognition tools.

FAQ

Q: What is this standard?

A: ISO 10303-111:2007 is Part 111 of the STEP (ISO 10303) family: an integrated application resource that defines elements for the procedural modelling of solid shapes so CAD construction history and feature definitions can be exchanged and reconstructed.

Q: What does it cover?

A: It covers data entities, parameters and relationships used to describe feature‑based and procedural modelling operations for solid geometry (extrusions, revolutions, sweeps, blends, chamfers, holes, patterns, boolean operations, etc.), expressed as an EXPRESS resource within the STEP modular architecture.

Q: Who typically uses it?

A: CAD and PLM vendors, implementers of STEP translators and conformance test suites, systems integrators, and engineering teams requiring robust CAD interoperability or the ability to preserve/reconstruct model construction history.

Q: Is it current or superseded?

A: The 2007 edition (Edition 1) is published and remains current; ISO has issued corrigenda (Cor 1: 2008 and Cor 2: 2014) and the publication was most recently confirmed in ISO’s systematic review (confirmed in 2024).

Q: Is it part of a series?

A: Yes — it is Part 111 of the ISO 10303 series (STEP). ISO 10303 is modular: Part 111 is an integrated generic resource intended to be used with other STEP resources and application protocols to support full product model exchange.

Q: What are the key keywords?

A: STEP, ISO 10303, procedural modelling, construction history, AP111, feature-based modelling, EXPRESS schema, CAD interoperability.
