Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 503: Application interpreted construct: Geometrically bounded 2D wireframe (ISO 10303-503:2000). This part of the ISO 10303 (STEP) family defines an application‑interpreted construct (AIC) for representing geometrically bounded two‑dimensional wireframe entities and their relationships for data exchange between CAD/CAM/PLM systems.

Abstract

ISO 10303-503:2000 specifies an application interpreted construct that captures geometrically bounded 2D wireframe information — i.e., 2D curve geometry together with the topological or geometric bounds that define finite wireframe features suitable for drafting, slicing, and 2D representation exchange. The document supplies data constructs that map the generic STEP resources into a coherent 2D wireframe representation intended for use by implementers of STEP application protocols and by software vendors exchanging 2D geometric data.

Scope

This standard defines an Application Interpreted Construct (AIC) for geometrically bounded two‑dimensional wireframe representations within the STEP framework (ISO 10303). Its scope covers the data structures, entity definitions and relationships required to represent bounded 2D curve geometry and associated annotation/contextual information so that 2D wireframe data can be exchanged reliably between CAx systems and archived in a vendor‑neutral format.

Key topics and requirements

• Definition of AIC entities for geometrically bounded 2D wireframe elements (curves, curve segments, bounds).
• Mapping between generic STEP resources and the 2D wireframe application constructs.
• Rules for representing bounded curve topology and geometric continuity in 2D.
• Conformance expectations for implementations exchanging bounded 2D wireframe data.
• Interoperability considerations with other STEP parts (resource modules and APs) when embedding 2D wireframe AICs.

Typical use and users

Primary users are implementers and integrators of STEP-based data exchange (CAD/CAM/CAE/PDM/PLM software vendors), systems engineers and developers creating import/export translators, and organizations performing long‑term archival of 2D engineering data. Typical uses include exchanging 2D bounded wireframe drawings, exporting 2D slice or profile geometry for downstream processing, and providing a standardized 2D geometry layer within larger STEP exchanges.

Related standards

ISO 10303-503 is part of the ISO 10303 (STEP) family. Closely related parts include other 5xx Application Interpreted Constructs such as ISO 10303-501, -502 and adjacent 5xx parts covering wireframe, surface and boundary representations; higher-level Application Protocols (APs) that consume 2D data (for example APs handling draughting and 2D/3D exchange); and core STEP resources and implementation parts (e.g., Parts 11, 21, and resource modules). A later edition (ISO 10303-503:2011) revises and replaces this 2000 edition.

FAQ

Q: What is this standard?

A: ISO 10303-503:2000 is a STEP Application Interpreted Construct that defines data constructs for representing geometrically bounded two‑dimensional wireframe information for product data exchange.

Q: What does it cover?

A: It covers the entity definitions, relationships and mapping rules needed to represent finite (bounded) 2D curve geometry and related topology so that 2D wireframe data can be exchanged between CAx systems in a vendor‑neutral form.

Q: Who typically uses it?

A: CAD/CAM/PLM software developers, implementers of STEP import/export translators, systems integrators, and organizations needing standardized 2D geometry exchange or archival.

Q: Is it current or superseded?

A: The 2000 edition is withdrawn and has been revised — it was superseded by a newer edition (ISO 10303-503:2011). Implementers should target the latest valid edition for current projects.

Q: Is it part of a series?
