- This paper describes the capabilities of a parametric model developed to perform design and analysis tasks in the areas of advanced engineering activities during the development of a new automotive product. The model focuses on selection of vehicle parameters for exterior shape specification, positioning of occupants in the vehicle space, and interior ergonomics considerations related to reach, clearances and vision. The model has been built using OpenGL to develop the required graphics functionality, C++ to incorporate the back end computations, and FLTK to develop the Graphical User Interface. The model, when fully developed, has the potential to be an interactive, multi-user, multi-disciplinary and comprehensive tool that can be used by any major automotive OEMs and suppliers, as well as by various universities as an instructional and teaching aid, for vehicle design.
