Full title and description

ISO 10303-523:2004 — Industrial automation systems and integration — Product data representation and exchange — Part 523: Application interpreted construct: Curve swept solid. This part of the STEP family defines an Application Interpreted Construct (AIC) for representing solids produced by sweeping a planar area along a directrix (curve), including variants where the directrix or area bounds are implicitly defined.

Abstract

Specifies the interpretation of integrated STEP resources to define a shape representation for implicitly defined solids created by sweeping operations. Solids are formed by sweeping a planar area along a directrix curve. For surface_curve_swept_area_solid both area and directrix are explicitly defined; for other swept_area_solid types the directrix may be implicitly defined (for example as a line or circle). For swept_disk_solid the area bounds are implicitly defined circles. The part provides the AIC-level rules and interpretation needed for consistent exchange and implementation.

Scope

Defines the Application Interpreted Construct (AIC) for curve-swept solids within the ISO 10303 (STEP) framework. The scope covers the interpretation and usage rules needed to represent solids produced by sweeping planar areas along directrix curves, including explicit and implicit definitions of the area bounds and directrix. The part is intended to be used with the integrated resources and EXPRESS schemas of STEP to ensure consistent representation and exchange of these swept solid shapes.

Key topics and requirements

• Definition of curve-swept solids (swept_area_solid variants).
• Rules for explicit and implicit directrix and area-bound representations (e.g., surface_curve_swept_area_solid, swept_disk_solid).
• Interpretation of STEP integrated resources to realize the AIC.
• EXPRESS-level modelling implications for shape representation and data exchange.
• Conformance guidance for implementers exchanging swept-solid geometry using STEP.

Typical use and users

Used by CAD/CAM/CAE software developers, data exchange and PLM system implementers, systems integrators, and organizations needing precise neutral-file representations of swept solids for interoperability, long-term data archiving, or model-based workflows. Also relevant to standards developers and validation/test-suite authors working in the STEP/ISO 10303 ecosystem.

FAQ

Q: What is this standard?

A: ISO 10303-523:2004 is a STEP Application Interpreted Construct that specifies how to represent solids created by sweeping a planar area along a directrix curve for consistent data exchange.

Q: What does it cover?

A: It covers the interpretation of integrated STEP resources needed to define curve-swept solids, including explicit and implicit forms of the directrix and area bounds, and the EXPRESS/representation-level rules for exchanging these shapes.

Q: Who typically uses it?
