Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1313: Application module: Mechanical design geometric presentation. This Technical Specification defines an application module within the ISO 10303 (STEP) family that specifies the data constructs and presentation attributes used to represent the visual presentation of mechanical-design geometry for data exchange and archival purposes.

Abstract

ISO/TS 10303-1313:2008 specifies the application module "Mechanical design geometric presentation". It covers structures and attributes for visual presentation of shape representations, assignment of visual attributes to geometric/topological items, projection algorithms for 3D-to-2D views, placement and layout of projections and multiple views, window background and colour handling, point/curve fonts and styles, predefined colours and curve styles, and interoperability with related STEP application modules.

Scope

The scope of ISO/TS 10303-1313:2008 is the machine-readable specification of presentation-related data needed to visualise mechanical design geometry in STEP-based exchanges. This includes definitions for how 3D shapes are projected into 2D views, how multiple views are arranged in a window, assignment of colour and style attributes to points, curves and surfaces, predefined palettes and styles, and linkages to camera/view and appearance layers modules to ensure consistent rendering across implementations. The module is intended as a reusable application module within the broader ISO 10303 architecture.

Key topics and requirements

• Data constructs for visual presentation of mechanical shape representations (points, curves, surfaces).
• Assignment and representation of presentation attributes: colour, font, curve style, line thickness, and style roles.
• Algorithms and rules for projecting 3D geometric entities into 2D views and placing those projections within view windows.
• Support for multiple views, view layouts, and window background settings to ensure consistent visual exchange.
• Interoperation with related application modules (e.g., camera view 3D and shape appearance layers) to compose complete presentation semantics.

Typical use and users

Primary users include CAD/CAM/CAE software developers, PLM and data-exchange implementers, systems integrators, and organisations that need neutral-format exchange or archival of mechanical design visual information. The module is used when implementations require standardized presentation semantics (colours, line styles, projections and view layouts) as part of STEP data exchanges or long-term archival.

Related standards

This Technical Specification is part of the ISO 10303 (STEP) family. It is designed to work with other STEP parts and application modules, including the interpreted construct for "Mechanical design geometric presentation" (ISO 10303-517), the Camera view 3D application module (ISO/TS 10303-1316), and Shape appearance layers (ISO/TS 10303-1009). For context about the overall ISO 10303 architecture and its role in CAD/CAM/PDM interoperability, refer to the ISO 10303 overview and fundamentals.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1313:2008 is a STEP application module (Technical Specification) that defines the data and rules required to represent the visual presentation of mechanical-design geometry for exchange and archival. It is part of the ISO 10303 family for product data representation and exchange.

Q: What does it cover?

A: It covers presentation-related constructs: assignment of visual attributes to geometric and topological items (colour, fonts, line/curve styles), projection algorithms for generating 2D views from 3D shapes, placement and layout of those projections, multi-view arrangements, predefined palettes/styles, and interfaces to camera/view and appearance modules.

Q: Who typically uses it?

A: CAD and PLM software developers, implementers of STEP translators and readers/writers, systems integrators working on CAD/CAM interoperability, and organisations needing a vendor-neutral representation of mechanical design presentation for exchange or long-term storage.

Q: Is it current or superseded?

A: ISO/TS 10303-1313 was published in December 2008 (Edition 1) and is listed as published within the ISO catalogue; it has been subject to periodic systematic review and confirmation actions (confirmed in ISO reviews as recently as late 2023). Users who need absolute current status should verify the ISO catalogue for any changes after 2023.

Q: Is it part of a series?

A: Yes — it is one application module within the ISO 10303 (STEP) series, which is the international family of standards for product data representation and exchange. The series includes many parts and application modules that together support CAD/CAM/PDM interoperability.

Q: What are the key keywords?

A: STEP, ISO 10303, presentation module, mechanical design, geometric presentation, projection, view layout, colour, curve style, application module, CAD data exchange.
