Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 101: Integrated application resources: Draughting. This part of ISO 10303 (STEP) defines the integrated resource constructs used to represent technical drawing information (sheets, views, annotations, dimensioning-related data and related drawing-level constructs) to support exchange, preservation and management of draughting information.

Abstract

ISO 10303-101:1994 specifies the elementary resources for representation of technical drawing information used in product definition. It covers the definition, description and management of drawings and drawing sheets, basic drawing annotations and aggregation of annotations for product information interpretation, and annotation elements used to express dimensions, tolerances and related measurement information. The part explicitly excludes certain management, visualization and generic annotation/style items that are provided by other parts of ISO 10303.

Scope

The 1994 edition defines the resource entities, relationships and structures necessary to represent draughting information within the STEP framework. Its scope includes the data constructs required to create, store and exchange drawing definitions, sheets, annotations, dimensions and basic tolerancing information, while excluding product-data management processes, visualization/view mechanisms and some generic annotation styles addressed in other ISO 10303 parts.

Key topics and requirements

• Resource constructs and entity definitions for drawings and drawing sheets (sheet identification, layout, referenced views).
• Annotation elements for textual and symbolic annotations used in technical drawings.
• Representation of dimensioning, tolerancing and measurement-related annotation semantics.
• Relationships between drawing-level entities and product definition data to support exchange and archival.
• Conformance to the STEP (ISO 10303) integrated resource model and compatibility with related resource parts.

Typical use and users

Primary users are CAD/CAM vendors, implementers of STEP-based data exchange solutions, system integrators, standards engineers, and organizations needing standardized exchange or long-term preservation of technical drawing data. The part is used as a reference when implementing application protocols or resource mappings for draughting information in STEP data exchanges.

Related standards

ISO 10303 is a multipart series; related parts include ISO 10303‑1 (overview and principles) and other resource parts covering coordinate systems, visualization, generic annotation styles and data management (for example parts addressing coordinate systems and visualization); many application protocols (APs) reference the integrated resources defined in Part 101. Subsequent revisions of Part 101 were published later (see revisions and superseding editions).

FAQ

Q: What is this standard?

A: ISO 10303-101:1994 is the draughting resource part of the STEP family (ISO 10303), specifying integrated resources for representing technical drawings and related annotations for product definition exchange.

Q: What does it cover?

A: It covers data constructs for drawing definitions, drawing sheets, basic annotations and dimensioning/tolerancing annotation semantics used when exchanging or preserving technical drawings in STEP format; it excludes certain management, visualization and generic annotation/style items addressed in other ISO 10303 parts.

Q: Who typically uses it?

A: CAD vendors, implementers of STEP translators, systems integrators, standards and PLM teams, and archival/records groups that require standardized draughting semantics for exchange or long-term retention of drawing data.

Q: Is it current or superseded?

A: The 1994 edition has been withdrawn and later revised. A corrigendum was issued in 1999; later editions of ISO 10303‑101 were published (editions in 2011 and 2014 were published and later withdrawn as new revisions appeared). The most recent published edition (as listed by ISO) is ISO 10303-101:2025 (published Nov 2025), which supersedes earlier editions.

Q: Is it part of a series?

A: Yes — ISO 10303 (commonly known as STEP) is a multipart international standard for product data representation and exchange; Part 101 is the draughting integrated resource part within that series and is intended for use by application protocols and implementers within the STEP framework.

Q: What are the key keywords?

A: STEP, ISO 10303, draughting, drawing annotation, dimensioning, tolerancing, integrated resource, CAD data exchange.
