9 AP214 UoF : main concepts alternative solutions are used to describe the variants of a product component, item instances are used to identify elements of an alternative solution, i.e. the t elements of a particular variant for a product component, design discipline item definitions are used to identify and describe parts or assemblies explicitly with their definitions, e.g. the geometric shape, for item instances product specifications are used to identify parts or assemblies as well as complete products implicitly by the product class and the chosen specifications physical instances are used to identify specific physically realized products or components, e.g. a chassis with a serial number. requires STEP resource Part 44 extensions Conclusions : STEP et l entreprise étendue Interopérabilité «Horizontale» Inter-services intra-entreprise Inter-entreprises entreprises en réseaux Géométrie (2D, 3D) PDM (Gestion technique) Documentation
