Abstract: This new design and innovation method has become very important in the automotive industry. As in art or architecture previously, generative engineering design has been adopted in mechanical engineering as the name used for this method. A common feature of all these fields is to use new programming environments, scripting capabilities, and feedback loops. The method ranges from simple mechanisms to relatively complex systems incorporating design evaluation routines. This paper focuses on the part of routine used for surface interpolation employing modern computer-aided design (CAD) software. Firstly, schemes and definitions for generative engineering design of surface-based automotive components are defined. Secondly, the paper deals with the procedure for accurate surface interpolation using 3D scanning of the designer's draft. The output is a class B surface of a shaped component appropriate for fitting functional parts too. Finally, the paper describes the procedure of generative design using simple illustrations of plastic components.

Keywords: surface interpolation; cloud of points; generative engineering design; class A surface; class B surface.
