Full title and description

ISO 10303-109:2004/Cor 1:2010 — Industrial automation systems and integration — Product data representation and exchange — Part 109: Integrated application resource: Kinematic and geometric constraints for assembly models. This entry refers to the original Part 109 (published December 2004) together with Corrigendum 1 published in 2010; the corrigendum corrects editorial/technical errors in the 2004 edition and is provided as a short PDF update to the main part.

Abstract

Part 109 specifies resource constructs for representing detailed geometric relationships between constituents of an assembly model, including geometric constraints between constituents, kinematic elements (kinematic pair and kinematic path), and representation of instanced assembly feature relationships at the geometric_representation_item level. The corrigendum (Cor 1:2010) issues limited corrections to the 2004 text.

Scope

Defines integrated application resource constructs needed to represent kinematic and geometric constraints within STEP assembly models. In scope are associations of shape aspect relationships to representations, instanced assembly feature relationship representations at the geometric_representation_item level, assembly geometric constraints, kinematic pairs and kinematic paths, and representation of a fixed constituent as the assembly anchor. Items explicitly outside the scope include product structure configuration management and tolerance information.

Key topics and requirements

• Data constructs for assembly-level geometric constraints and kinematics (kinematic pair, kinematic path).
• Association mechanisms between shape aspects/instanced assembly features and their geometric representations.
• Representation at the geometric_representation_item level to support detailed assembly relationships and analyses.
• Definition of a fixed constituent (anchor) within an assembly model.
• Corrigendum provisions: editorial and technical corrections issued in 2010 to amend the 2004 text.

Typical use and users

Used by CAD/CAM/CAE and PLM software vendors implementing STEP (ISO 10303) resources, systems integrators exchanging assembly and kinematic data, tool developers building STEP import/export modules, and standards/quality engineers validating product model exchange. It is especially relevant to implementers of STEP application protocols and integrated application resources who require consistent assembly-constraint semantics.

Related standards

Part of the ISO 10303 (STEP) family. Closely related documents include other integrated application resources and application protocols in the 101–199 and 201–299 ranges (for example APs that consume integrated resources), plus the STEP implementation and conformance parts (parts 11–39 and 301–399). Corrigendum 2 (2014) and other errata for Part 109 are also part of the lifecycle.

FAQ

Q: What is this standard?

A: ISO 10303-109:2004 is a STEP integrated application resource that defines how to represent kinematic and geometric constraints for assembly models; Cor 1:2010 is a published corrigendum that corrects the original 2004 text.

Q: What does it cover?

A: It covers data constructs and representation rules for assembly-level geometric and kinematic relationships (assembly geometric constraints, kinematic pair/path, shape-aspect associations, instanced feature relationship representation) but does not cover product-structure configuration management or tolerance specifications.

Q: Who typically uses it?

A: CAD/CAM/CAE vendors, PLM/PDM system implementers, software engineers creating STEP import/export or validation tools, and standards committees or quality engineers concerned with interoperable exchange of assembly and kinematic data.

Q: Is it current or superseded?

A: The 2004 edition remains the published edition for Part 109; Corrigendum 1 (2010) and subsequent corrigenda (for example Cor 2:2014) amend that edition. Users should consult the ISO central record for the latest status and any additional corrigenda or amendments.

Q: Is it part of a series?

A: Yes — it is part of the ISO 10303 (STEP) series of standards for product data representation and exchange; Part 109 is one of many integrated application resources that support application protocols and implementation methods across the STEP family.

Q: What are the key keywords?

A: STEP, ISO 10303, integrated application resource, kinematic constraints, geometric constraints, assembly model, corrigendum.
