Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 112: Integrated application resource: Modelling commands for the exchange of procedurally represented 2D CAD models. This part of ISO 10303 (STEP) defines standardized representations for a set of modelling commands used to exchange procedurally represented 2D CAD data such as sketches and profiles.

Abstract

ISO 10303-112:2006 specifies a standardized representation of procedural modelling commands for 2D CAD models. Procedural representations are expressed as sequences of modelling commands; this part defines those commands and their representation to enable consistent exchange of procedurally represented 2D CAD content (for example sketches or profiles) between systems.

Scope

ISO 10303-112 defines the information representation required to exchange procedural (command-based) 2D CAD models. Its scope covers the definition of a set of modelling commands and their data representations so that sequences of commands (procedural histories) producing 2D geometry—such as sketches and profiles—can be represented, transmitted and interpreted by different CAD and downstream systems. The part is intended to integrate with other STEP resources and application protocols within the ISO 10303 family.

Key topics and requirements

• Definition of a standardized set of 2D modelling commands used to represent procedural construction histories.
• Data structures and schema-level representations required to encode sequences of modelling commands.
• Support for common 2D constructs used in sketches and profiles (lines, arcs, splines, constraints, parametric operations where applicable).
• Compatibility and harmonization with other STEP parts and integrated resources to allow combined exchange of procedural and explicit geometry.
• Requirements for unambiguous interpretation of procedural sequences by receiving applications.
• Conformance considerations for implementers exchanging procedurally represented 2D models.

Typical use and users

Implementers and integrators of CAD, CAM and PDM systems who need to exchange 2D procedural or history-based representations; CAD software vendors creating import/export translators; engineering data managers seeking neutral archival formats for 2D construction histories; researchers and tool vendors working on parametric and feature-based interoperability.

Related standards

ISO 10303-112 is a part of the ISO 10303 (STEP) family. Closely related parts and topics include the core STEP description methods (for example the EXPRESS language and STEP-file formats), other integrated resources and application protocols that cover geometric and product data exchange, and application modules that provide shared building blocks for APs. Implementations typically coordinate Part 112 usage with relevant APs (for 3D geometry exchange and product model data) and with the Integrated Resources used across STEP.

FAQ

Q: What is this standard?

A: ISO 10303-112:2006 is a part of the STEP family that defines an integrated application resource for representing modelling commands used to exchange procedurally represented 2D CAD models (e.g., sketches and profiles).

Q: What does it cover?

A: It covers the standardized representation of sequences of 2D modelling commands—the procedural construction history—so that such procedural data can be reliably exchanged between systems and interpreted consistently by receivers.

Q: Who typically uses it?

A: CAD and CAM software vendors, implementers of STEP translators, PDM/PLM integrators, engineering data managers, and researchers working on CAD interoperability and archival of procedural 2D data.

Q: Is it current or superseded?

A: ISO 10303-112 was published in December 2006 (Edition 1). The standard has been subject to periodic five-year reviews and was confirmed as current in the ISO review cycle; implementations should check the latest ISO catalog confirmation status for any subsequent updates or confirmations.

Q: Is it part of a series?

A: Yes. Part 112 is one resource within the broader ISO 10303 (STEP) series, which is composed of many parts (integrated resources, application protocols and modules) covering different aspects of product data representation and exchange.

Q: What are the key keywords?

A: STEP, ISO 10303, procedural modelling, 2D CAD, modelling commands, sketches, profiles, interoperability, EXPRESS.
