A Practical Methodology for Creating Robust Parametric Surface-based Models in Automotive Engineering

The paper deals with the general description of Generative Engineering Design (GED) methodology used during the development of surface-based components. The stages of GED presented here are applied on sport vehicle parts with visible surfaces. The focus is on the later stages, i.e. detail design. These include creation of robust parametric shape-based CAD model, which is capable of easy change propagation. The GED methodology builds on Knowledge-Based Engineering (KBE) principles, because the ability of quick and easy change is essential. The practical use of the methodology is demonstrated using CAD-based generic templates and a custom tool in CATIA.
