Full title and description

ISO 10303-501:2000 — Industrial automation systems and integration — Product data representation and exchange — Part 501: Application interpreted construct: Edge based wireframe. This part of ISO 10303 defines the interpretation of integrated resources to represent three-dimensional product shape using wireframe models composed of connected edge sets and vertices.

Abstract

This part specifies how to interpret STEP integrated resources to represent wireframe geometry: points in 3D coordinate space, curves including B‑splines, edges and connected edge sets that form one or more wireframe models or assemblies. It targets wireframe models where edges meet only at vertices and connected edge sets do not overlap or intersect except at vertices or edges.

Scope

Defines an Application Interpreted Construct (AIC) for edge‑based wireframe representation within the ISO 10303 (STEP) framework. The standard covers the representation of wireframe models as graphs of edges and vertices, the definition of connected edge sets, coordinate points, parametric and spline curves in three‑dimensional space, and the representation of single models or assemblies built from such wireframe elements. It is intended to interpret the integrated resources of STEP to meet these representation requirements.

Key topics and requirements

• Definition of an edge‑based wireframe application interpreted construct (AIC).
• Representation rules for points, parametric curves and B‑splines in 3D space.
• Graph-based modelling: edges and vertices with intersection rules (edges intersect only at vertices).
• Connected edge sets: non-overlapping/ non-intersecting edge sets except at permitted boundaries.
• Support for single wireframe models and assemblies composed of wireframe components.
• Mapping and interpretation rules that integrate STEP integrated resources (EXPRESS schemas) into application-level constructs.

Typical use and users

Used by CAD/CAM/CAE vendors, implementers of STEP data exchange, PLM and PDM system integrators, software engineers building neutral CAD translators or archival systems, and researchers working with geometric data exchange. Typical use cases include transferring legacy or simplified geometry as wireframe between systems, interoperability testing, and storing simple geometric representations for archival or downstream processing.

Related standards

ISO 10303 is a family of STEP standards; Part 501 is one of the Application Interpreted Constructs (AICs). Related nearby parts include other AICs and application protocol parts (for example ISO 10303‑505 and ISO 10303‑519) as well as numerous APs and integrated resources that together form the STEP suite used for product model data exchange.
