Описание (английский):

Procedural representations are expressed as sequences of modelling commands. ISO 10303-112:2006 defines standardized representations for a set of modelling commands for the exchange of procedurally represented 2D CAD models, including sketches or profiles.

Overview

ISO 10303-112:2006 is part of the ISO 10303 (STEP) family and defines an Integrated Application Resource for exchanging procedurally represented 2D CAD models. The standard specifies how procedural representations-expressed as sequences of modelling commands-are represented so sketches and profiles (2D geometry created by operations) can be reliably exchanged between systems. The document includes EXPRESS schemas, function definitions and examples to support computer-interpretable transfer of procedural sketch data.

Key topics and requirements

Procedural sketch model: Represents 2D sketches as ordered modelling commands (construction history) rather than only final geometry.

Standardized command set: Defines many sketch operations such as:

line and polyline creation (create_line_segment*, create_polyline)
circle and arc creation (create_circle*, create_circular_arc*)
ellipse, spline, parabolic arc, fillet, chamfer
pattern and transform operations (translate, rotate, mirror, scale, pattern_rectangular, pattern_circular)

Explicit constraints and history: Support for representing construction history and explicit geometric constraints within a sketch.

Entity and function definitions: Includes procedural_sketch entity definitions, function definitions (distance_between_cartesian_points, midpoint, etc.), and type definitions used by commands.

Machine-readable artifacts: Contains EXPRESS-G diagrams, computer-interpretable listings, and normative annexes for entity short names and information object registration.

Normative and informative content: Normative references and annexes (A, B) and informative examples (Annex E) to illustrate intended usage.

Applications and practical value

CAD interoperability: Exchange of sketches/profiles between different 2D/3D CAD applications while preserving construction intent.

PLM and data archival: Storing procedural sketch definitions in product data repositories to retain editability and traceability.

Downstream manufacturing: Supplying accurate sketch definitions to CAM, CNC programming, tooling and simulation systems where construction history or constraints matter.

Software development: Implementing import/export, translators, and validation tools that consume STEP-based procedural sketch data.
