Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1509: Application module: Manifold surface (ISO/TS 10303-1509:2008). This technical specification defines an application module within the ISO 10303 (STEP) family that specifies data constructs and exchange semantics for manifold surface geometry, curves and related topological constructs used in CAD/CAM and product-data exchange.

Abstract

ISO/TS 10303-1509:2008 specifies the STEP application module for Manifold surface. The module covers representation of 3D points and parameter-space points, 3D and parameter-space curves (including elementary curves such as line, circle, ellipse, parabola and hyperbola), intersection curves, polylines, elementary surfaces (plane, cylinder, cone, torus, sphere), swept and sculptured surfaces, trimming and composition of curves and surfaces using topological entities, replication and 3D offsets of curves and surfaces, and items within the scope of the Topologically bounded surface application module (ISO/TS 10303-1511).

Scope

This application module defines data types, relationships and constraints required to represent manifold surface geometry and associated curve and topological items for interchange using STEP (ISO 10303). It addresses point and curve definitions in both 3D space and parameter spaces of curves/surfaces, standard elementary curve and surface forms, swept and sculptured surface constructions, trimming and composition operations, replication and offset operations, and interactions with topologically bounded surface constructs. The module is intended to be used as a building block for higher-level application protocols and CAD data exchanges.

Key topics and requirements

• Definitions for 3D points and parameter-space points.
• Representation of 3D curves and curves defined in surface parameter space (including line, circle, ellipse, parabola, hyperbola).
• Intersection curves and support for polylines of three or more points.
• Elementary surfaces (plane, cylinder, cone, torus, sphere) and swept surfaces (rotation, linear extrusion).
• Sculptured (free-form) curves and surfaces and trimming/composition using topological entities.
• Replication and 3D offsets of curves, surfaces and surface models.
• Interoperability requirements with related application modules (for example, Topologically bounded surface — ISO/TS 10303-1511).

Typical use and users

Used by CAD/CAM/CAE software developers, STEP implementers, system integrators, PDM/PLM vendors and engineering teams needing standardized exchange of manifold surface geometry between systems. Also useful for implementers of higher-level STEP application protocols and for organizations performing long-term archival or interoperability validation of geometric product data. For context on the broader STEP family and typical domains of application (mechanical design, manufacturing, aerospace, automotive, etc.), see general ISO 10303 guidance.
