Full title and description

ISO 10303-202:1996 — Industrial automation systems and integration — Product data representation and exchange — Part 202: Application protocol: Associative draughting. This part of ISO 10303 (STEP) defines the information structures and rules needed to represent and exchange computer-interpretable technical drawings and associated product-definition data for associative draughting workflows.

Abstract

Part 202 specifies how to use integrated STEP resources to meet the information requirements of associative draughting, enabling inter-organization exchange of drawing information and linked product-definition data. It covers representation of drawing entities and hierarchy, administrative data for drawing management, and the presentation of dimensions and annotations.

Core bibliographic and lifecycle facts above are taken from the ISO catalogue entry for ISO 10303‑202:1996. The record also shows the standard was withdrawn (01 December 2014) and later superseded by ISO 10303‑242:2014.

Scope

ISO 10303‑202 defines an application protocol for associative draughting: the set of STEP resources, entity definitions and information models required to represent technical drawings in a computer-interpretable form and to exchange them between organizations. The scope includes drawing structure and hierarchy, management/administrative metadata for drawings, and conventions for presenting dimensions and annotations so downstream systems can interpret, render, and maintain associations between drawing views and product-definition data.

Key topics and requirements

• Definition of drawing representation structures and hierarchical composition (sheets, views, symbols, annotations).
• Rules for linking drawing elements to product-definition items (associativity between drawing geometry and product model data).
• Administrative and management data for drawing revision, identification and lifecycle control.
• Presentation rules for dimensions, tolerances, text annotations and graphic symbols.
• Use of STEP integrated resources and EXPRESS-based data definitions to ensure interoperability with other ISO 10303 parts and implementation methods.

The above topics follow the AP202 intent to enable interchange of computer-interpretable drawing data as part of the broader STEP family.

Typical use and users

Typical users include CAD/CAM developers, PDM/PLM and engineering data managers, manufacturers who exchange technical drawings between organizations, archives and data custodians preserving long-term technical documentation, and systems integrators implementing STEP-based interchange solutions. AP202 was used where associativity between 2D drawing elements and product-definition data was required.

Related standards

ISO 10303-202 is part of the ISO 10303 (STEP) family. It has been withdrawn and replaced by later work in AP242 (ISO 10303-242:2014) which consolidates and modernizes drawing, geometry and product-definition exchange capabilities. Other related parts and resources in the STEP framework include implementation methods (Part 21 STEP-File), description methods (Part 11 EXPRESS), and integrated resources (e.g., Part 41 fundamentals) as well as other application protocols (for example AP203, AP214) that address related CAD/PLM exchange needs.

FAQ

Q: What is this standard?

A: ISO 10303-202:1996 is Part 202 of ISO 10303 (STEP) — an application protocol that defines how to represent and exchange associative technical drawings and associated product-definition data.

Q: What does it cover?

A: It covers the information model and use of STEP resources to represent drawing structure and hierarchy, administrative/drawing-management data, and the presentation of dimensions and annotations to support computer-interpretable draughting and inter-company exchange.

Q: Who typically uses it?

A: CAD/CAM software vendors, engineering departments, PDM/PLM system integrators, manufacturers exchanging drawings between organizations, and archival/data preservation teams. Use is focused where associativity between drawing elements and the product model is required.

Q: Is it current or superseded?

A: ISO 10303-202:1996 has been withdrawn (withdrawal recorded 01 December 2014) and the relevant capabilities have been superseded and consolidated in later STEP work, notably ISO 10303-242:2014 (AP242). For new projects AP242 or current STEP deliverables are recommended.

Q: Is it part of a series?

A: Yes — it is one application protocol within the ISO 10303 (STEP) family, which contains many parts covering description methods, implementation methods, integrated resources, application protocols and modules for product-data representation and exchange.

Q: What are the key keywords?

A: STEP, AP202, associative draughting, drawing exchange, CAD interoperability, EXPRESS, product data representation.
