Full title and description

ISO 10303-517:2000 — Industrial automation systems and integration — Product data representation and exchange — Part 517: Application interpreted construct: Mechanical design geometric presentation. This part of ISO 10303 (STEP) defines an application interpreted construct (AIC) for the visual presentation of mechanical-design geometric information, specifying the EXPRESS schema, data constructs and presentation attributes used to describe points, curves, surfaces, topology and basic presentation attributes (colour, line fonts, view and projection rules) for mechanical design geometry.

Abstract

ISO 10303-517:2000 provides a machine-readable information model (an AIC) that describes how geometric and topological elements used in mechanical design are to be presented visually. It focuses on mapping geometry and topology to presentation attributes (colour, line style, viewport placement, simple 3D–2D projection and multi-view arrangement) to support consistent visualization and data exchange between CAD and visualization systems. Advanced rendering features (lighting models, material reflectance, layered annotations, or complex rendering techniques) are intentionally out of scope.

Scope

This part specifies an application interpreted construct (AIC) intended for the presentation of mechanical-design geometric data. It defines the EXPRESS schema and constructs to: assign basic presentation attributes (colour, line fonts) to geometric and topological elements (points, curves, surfaces, faces, edges), define view windows and multi-view arrangements, provide algorithms or rules for simple 3D-to-2D projections and placement within a view, and distinguish roles of boundary and grid curves used to describe surfaces. Exclusions include annotation/annotation styles, advanced rendering properties (lighting, reflectance), layer assignments, and complex shading/hiding algorithms.

Key topics and requirements

• EXPRESS schema for a presentation AIC tailored to mechanical design geometry.
• Entities and types for points, curves, surfaces and topological relationships with presentation attributes.
• Assignment of visual attributes: colour, line style, point and curve fonts.
• Window/view definitions, multi-view layout and simple projection rules for 3D-to-2D display.
• Role-based distinctions for boundary curves and grid/defining curves on surfaces.
• Interoperability rules intended for use in the context of a STEP application protocol (AP) implementation.

Typical use and users

Used by CAD system developers, visualization and rendering tool vendors, implementers of STEP/APs and integrators exchanging mechanical-design data between systems. Typical users include mechanical design engineers, CAD data-exchange specialists, software architects implementing STEP import/export, and downstream visualization tool developers who require a standardized presentation mapping for exchanged geometry.

Related standards

ISO 10303 is a multipart family (STEP). ISO 10303-517:2000 was issued with Corrigendum ISO 10303-517:2000/Cor 1:2002 and subsequently revised by later editions (notably ISO 10303-517:2011) and later versions of the part have been published (ISO 10303-517:2022 listed in the ISO catalogue). This AIC is intended to be used in the context of relevant APs and related abstract test suites such as parts dealing with mechanical design presentation, boundary representation APs and application modules addressing geometric presentation and testing.

FAQ

Q: What is this standard?

A: ISO 10303-517:2000 is a part of the STEP family that defines an application interpreted construct for the visual presentation of mechanical-design geometry—an EXPRESS schema and related rules for mapping geometry/topology to presentation attributes.

Q: What does it cover?

A: It covers the EXPRESS data definitions and presentation rules for points, curves, surfaces and topology used in mechanical design, including assignment of basic visual attributes (colour, line font), view/window definitions, multi-view arrangements and simple projection algorithms. It does not cover advanced rendering (lighting, material reflectance), annotations, layered assignments or complex shading/hiding techniques.

Q: Who typically uses it?

A: CAD vendors, implementers of STEP application protocols, visualization-tool developers, and engineers or integrators exchanging mechanical design geometry who need a standardized presentation model.

Q: Is it current or superseded?

A: The 2000 edition is withdrawn. It was issued with a corrigendum in 2002 and later revised; ISO’s catalogue shows subsequent revisions of part 517 (for example a 2011 revision and a later version listed as 2022). Implementers should refer to the most recent published edition of part 517 for current normative text.

Q: Is it part of a series?

A: Yes — ISO 10303 is a multipart family (commonly called STEP). Part 517 is one of many parts (APs, AICs, modules and ATSs) addressing different application areas; it is intended to be used together with application protocols and integrated resources within the ISO 10303 framework.

Q: What are the key keywords?

A: STEP, AIC, geometric presentation, mechanical design, EXPRESS, CAD interchange, visualization, colour, line style, projection, view layout.
