The exterior design of cars is considered to be a highly creative task typically executed by experienced human designers. Based on a case study of the Audi car family, both a careful analysis of the human-assisted exterior design process has been assessed, as well as the syntax, semantics and pragmatics of a formal, graph-based engineering design language for the exterior design of cars with class A surface quality has been created. The design language allows for the almost complete reconstruction of the exterior design of the Audi car family (only smaller details such as side and rear mirrors, door seals, etc. have been omitted) and is demonstrated in this study to be able to re-engineer the exterior of an Audi A3 Sportsback. The syntax of this styling language consists of so- called characteristic lines and elements ('design genes', according to consistently used company terminology) and is used to create a graphical representation of an Audi specific design graph. The design graph is automatically translated into a 3D-CAD model using CATIA V5 as the geometry engine and is finally subject to a visual surface quality check using the isophotic analysis menu in CATIA V5.
