It is pointed out that the digitization of car styling process is an inevitable trend. At present, some of the proposed digital processes or techniques for car styling owing the same disadvantage that they have sacrificed designers’ intuition in design process and broken designer''s thinking habit. As a result, designers cannot begin their work in practice with these methods. Tape drawing is a drawing skill using curve tape. It let designers render and modify a car in the full size easily and it is quite an important and ideal tool in car styling. After reviewing the related technology of CAD, including definitions and requirements of the and Class-A surfaces as well as the characteristics of B-spline curve, a new design process integrating CAD and conventional drawing skill for car styling is proposed. By using advantage of tape drawing, it help designers to exert their creativity and modify the digital model with it, instead of using the mouse and keyboard whose interface are not intuitive. The physical tape drawing is digitalized through CAD technology, in order to realize the design mode of modifying the digital model with physical tape drawing. In the end, the reasonable parameters are determined through running the algorithm and an empirical case has been did to prove the feasibility of this process.
