Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1003: Application module: Curve appearance (ISO/TS 10303-1003:2008). This Technical Specification defines the data constructs used to represent visual appearance information for curves within the ISO 10303 (STEP) application module framework.

Abstract

ISO/TS 10303-1003:2008 specifies the application module for curve appearance, including the definition of appearance information for curves and its relationships to styled-curve constructs. The document describes data items needed to express color, style and other presentation attributes applicable to curve geometry in STEP-based data exchange.

• Number of pages: 45.

Scope

The specification covers the definition of appearance information applicable to curve entities within the STEP application module structure. It addresses attributes and constructs required to represent how curves are presented (for example: color, line style, visibility and associations to styled-curve concepts) and defines items that are used by or referenced from related application modules such as Styled curve. The module is intended to be used where product data needs to include presentation and visualization information for curves.

Key topics and requirements

• Data schema for curve appearance: entities and attributes to capture visual properties of curve geometry (color, line style, thickness, visibility).
• Relationships to styled-curve constructs and higher-level appearance modules (ensuring consistency with Styled curve and Appearance assignment modules).
• Interoperability requirements for exchanging presentation attributes within STEP-compliant files and application modules.
• Rules for assignment and referencing of appearance items to curve representation items.

Typical use and users

Implemented by CAD/CAM/CAE and PLM software vendors, data-exchange tool developers, system integrators and standards engineers working with STEP-based interchange formats. Typical use cases include exchanging visualization/presentation details of curves between design systems, preserving presentation when archiving STEP models, and implementing application modules that combine geometry with presentation metadata.

Related standards

This application module is part of the ISO 10303 (STEP) family and is intended to be used alongside related appearance and representation modules such as ISO/TS 10303-1001 (Appearance assignment), ISO/TS 10303-1006 (Foundation representation), and modules addressing styled curve constructs (e.g., ISO/TS 10303-1749). The 2008 edition has later revisions and a published version from 2019 that supersedes earlier withdrawn editions.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1003:2008 is a Technical Specification in the ISO 10303 family that defines the application module for curve appearance — the data constructs used to represent visual/presentation attributes of curve geometry in STEP.

Q: What does it cover?

A: It covers the definition and assignment of appearance information for curves (color, line style, visibility and related presentation metadata) and how those items integrate with styled-curve constructs and other STEP application modules.

Q: Who typically uses it?

A: CAD/CAM/CAE and PLM software developers, data-exchange implementers, systems integrators, and standards practitioners working with STEP-based product data exchange and visualization. They use it to preserve or communicate how curves should be presented across systems.

Q: Is it current or superseded?

A: The 2008 edition is listed as withdrawn and a later revision/edition of part 1003 was published in 2019; users should prefer the 2019 published version for current implementations.

Q: Is it part of a series?

A: Yes. It is part of the ISO 10303 (STEP) series of standards (application modules are in the 1001–1999 range) that together define data models and application modules for product data representation and exchange.

Q: What are the key keywords?

A: Curve appearance, presentation, STEP, ISO 10303, application module, styled curve, visualization, appearance assignment.
