ISO/TS 10303-203:2005

ISO/TS 10303-203:2005 specifies the application protocol for configuration controlled three-dimensional design of parts and assemblies.

The following are within the scope of ISO/TS 10303-203:2005:

• products that are three dimensional mechanical parts and assemblies;
• product definition data and configuration control data pertaining to the design phase of a product's development;
• representation of an instance of a part in an assembly through its usage in a sub-assembly;
• six groups of shape representations of a part that includes advanced boundary representation, faceted boundary representation, manifold surfaces with topology, geometrically bounded surface and wireframe geometry, wireframe with topology, and constructive solid geometry in three-dimensions;
• geometric validation properties to allow the translation of geometric shape representations (advanced boundary representation and faceted boundary representation solids) to be checked for quality;
• geometric presentation of geometric shape representations by the application of colours, layers and groups;
• geometric and dimensional tolerances applied to geometric shape representations;
• textual annotation and notes applied to geometric shape representations.

This part of ISO 10303 conforms to ISO 10303-11:2004, and is harmonized with ISO 10303-214.
