Full title and description

Technical product documentation — Digital product definition data practices. This International Standard specifies requirements for the preparation, revision and presentation of digital product definition data sets, supporting both 3D model‑only and 3D model with 2D drawing workflows and providing guidance for CAD/CAx modelling and annotation practices.

Abstract

The document defines requirements that complement existing technical product documentation standards, organising common requirements for both supported application methods (3D model‑only and 3D model plus 2D drawing) and identifying any essential differing requirements. It aims to improve modelling, annotation and data‑set practices for design, engineering and CAx software development, and refers to established interpretation rules from standards such as ISO 129‑1 and ISO 1101.

Scope

Specifies requirements for the preparation, revision and presentation of digital product definition (DPD) data sets used as technical product documentation. The standard supports two application methods — 3D model‑only and 3D model with associated 2D drawing in digital format — and provides common requirements plus any specific provisions needed for each method. It is intended to be used alongside existing GPS/TPD standards for interpretation and tolerancing rules.

Key topics and requirements

• Requirements for structuring and presenting digital product definition data sets (DPD).
• Support for two application methods: 3D model‑only and 3D model with 2D drawing in digital format.
• Guidance on modelling and annotation practices to support model‑based definition (MBD) and product manufacturing information (PMI).
• Compatibility considerations for CAD/CAx systems and recommendations for CAx software developers.
• Reference to interpretation rules from established TPD/GPS standards (for example ISO 129‑1 and ISO 1101).

Typical use and users

Used by product designers, CAD engineers, technical authors, quality and configuration managers, manufacturing engineers, and CAx software developers to define and manage digital product definition deliverables and workflows (model‑based definition, PMI and associated metadata) in engineering and industrial organisations.

Related standards

Commonly associated or referenced standards include ISO 129‑1 (presentation of technical product documentation), ISO 1101 (geometrical product specifications — geometrical tolerancing), ISO 10303 (STEP — product data representation and exchange) and the previous edition ISO 16792:2015 (withdrawn; revised by the 2021 edition).

FAQ

Q: What is this standard?

A: ISO 16792:2021 is an International Standard that specifies requirements and good practices for preparing, revising and presenting digital product definition data sets used as technical product documentation.

Q: What does it cover?

A: It covers the organisation and presentation of digital product definition (DPD) data sets, supports both model‑only and model+drawing application methods, and provides guidance on CAD modelling, annotation and CAx interoperability while referencing established interpretation rules from related GPS/TPD standards.

Q: Who typically uses it?

A: Engineers and designers producing model‑based deliverables, technical documentation specialists, manufacturing and quality engineers, configuration managers, and CAx software developers use this standard to establish consistent DPD practices.

Q: Is it current or superseded?

A: ISO 16792:2021 (Edition 3, published April 2021) is the current published edition and replaces ISO 16792:2015 (withdrawn). The standard is subject to periodic review by ISO.

Q: Is it part of a series?

A: It sits within the family of technical product documentation and GPS/TPD standards and is typically used together with related standards such as ISO 129‑1 and ISO 1101; it is the latest published edition of the ISO 16792 line of standards.

Q: What are the key keywords?
