Study of complex car-body part automatically modeling

In general, car body parts are very complex models by thousands of differential geometrically operations. For the computer-aided car-body part automatic modeling system, this complexity is a big challenge. This paper proposes a new body-based modeling method, using body-based features and a "sculpturing" strategy to create complex model via a computer car-body parts design system. This method is helpful for increasing stability of geometric modeling and flexibility of modification in computer car-body parts design system, and favorable for creating more flexible model for further changing based analysis and optimization.
