ISO 10303-203:2011 specifies the application protocol for Configuration control 3d design ed2.

The following are within the scope of ISO 10303-203:2011:

• products that are 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;
• three dimensional shape representations of a part that includes:
  • geometrically and topologically bounded wireframe models;
  • geometrically bounded surface models;
  • topologically bounded solid models with facetted, elementary and advanced faces;
  • non surface bounded solid models including constructive solid geometry, curve swept and other swept solids, thickened face solid;
  • solids with construction history;
  • topologically bounded manifold surface and subsurface and non manifold surface models;
  • topologically bounded compound models;
• 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 and dimensional tolerances applied to geometric shape representations;
• materials and their composition of chemical substance;
• composite material structure and shape;
• catalogue data characterized by property value pairs;
• three dimensional presentation of product data:
  • arranging geometric elements in layers and groups and assigning colours;
  • presentation styles for points, curves, surfaces and sections, including hatching and tiling;
  • saved views of particular camera positions and sections;
  • textual annotation and notes applied to geometric elements;
  • presentation of geometric and dimensional tolerances;
• technical drawings as two dimensional presentation of product data.
