Full title and description

ISO 10303-46:1994 — Industrial automation systems and integration — Product data representation and exchange — Part 46: Integrated generic resources: Visual presentation. This entry relates specifically to the Technical Corrigendum 1 published in 1999 (ISO 10303-46:1994/Cor 1:1999), which corrects and clarifies parts of the 1994 edition.

Abstract

Specifies integrated generic resources to support visualization of product data: association of product and presentation data, presentation style attributes, approximation tolerances for geometric presentation, character and symbol appearance (fonts), layer-based image control and nesting of presentation areas. It excludes definition of product information content and pure graphical-only exchanges not tied to product data. (Applies as a corrigendum to the 1994 Part 46 text.)

General information

• Status: Withdrawn (corrigendum published and later withdrawn along with the underlying edition).
• Publication date: Corrigendum 1 published July 1999 (original Part 46 published December 1994).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control / industrial data).
• Edition / version: Edition 1 (1994) with Technical Corrigendum 1 (1999) — referenced as ISO 10303-46:1994/Cor 1:1999.
• Number of pages: Corrigendum: 14 pages. (The original 1994 Part 46 main document is substantially longer — the 1994 edition is listed as 211 pages.)

Scope

Defines the generic presentation resources needed to represent and exchange the visual appearance of product data within the STEP framework (ISO 10303). Includes presentation styles, mapping between product and presentation elements, font and symbol definitions (and references to external font resources), tolerance handling for geometric presentation, layer control and nested presentation areas. It does not define the product data models themselves or the internal contents of external font/symbol libraries.

Key topics and requirements

• Association mechanisms between product data and presentation elements (linking model geometry with display attributes).
• Presentation style attributes (color, line style, shading, visibility and emphasis rules).
• Control of geometric approximation tolerances for presentation geometry.
• Definition and referencing of character fonts and symbol sets for consistent textual/symbol presentation.
• Layering mechanism for image control and nesting of presentation areas for complex displays.
• Compatibility and conformance considerations with other ISO graphics and STEP parts to ensure interoperable visualization.

Typical use and users

Used by standards implementers, CAD/PLM software vendors, system integrators and technical data exchange architects who need to ensure consistent visualization of product information exchanged via STEP. Also referenced by organizations integrating multi-vendor product data where visual presentation must be preserved. Typical activities include implementing STEP presentation resources, mapping application-specific display rules to standard presentation constructs, and validating exchanged visualization content.

Related standards

Part of the ISO 10303 (STEP) series. Related items include the base ISO 10303-46:1994 text (to which this corrigendum applies), subsequent corrigenda and later revisions of Part 46 (notably later consolidated editions and revisions published after 1994, and later editions that superseded the 1994 edition). Implementers should consult the current/revised Part 46 edition for up-to-date normative content.

FAQ

Q: What is this standard?

A: ISO 10303-46:1994/Cor 1:1999 is a technical corrigendum that corrects and clarifies portions of ISO 10303-46:1994 — the Part of STEP that specifies integrated generic resources for visual presentation of product data.

Q: What does it cover?

A: It covers the presentation resources needed to represent and exchange the visual appearance of product information (styles, fonts, symbols, layers, tolerances and product-to-presentation associations), but does not redefine product model content or the internal contents of external font libraries.

Q: Who typically uses it?

A: CAD/PLM software developers, data exchange specialists, systems integrators and organizations implementing STEP-based exchanges where preservation of visual presentation is required.

Q: Is it current or superseded?

A: The 1994 edition and its corrigenda (including Cor 1:1999) have been withdrawn and later revisions of Part 46 have been issued. Users should consult the most recent Part 46 edition (the ISO catalogue shows later consolidated revisions) for current normative content.

Q: Is it part of a series?

A: Yes — it is Part 46 of the ISO 10303 (STEP) family of standards for product data representation and exchange. The STEP series contains many parts addressing schemas, application protocols, resources and implementation methods.

Q: What are the key keywords?

A: STEP, ISO 10303, visual presentation, integrated generic resources, presentation style, fonts, symbols, layering, product-to-presentation mapping.
