Abstract: With the application of "Fast modeling" technology based on subdivision in the field of automobile styling by global automobile enterprises, more and more automobile styling practitioners begin to learn and study this new modeling technology. This paper will start with the advantages and disadvantages of subdivision modeling compared with the traditional non-uniform rational b-splines (NURBS) modeling, briefly describe the significance of subdivision modeling and its application stage. Then briefly introduce the CATIA IMA (Image&Shape) module and its common commands. Finally, a larger space is used to descrcribe the specific implementation methods, modeling ideas and skills of "fast modeling" based on CATIA IMA, it is intended to enable the relevant practitioners to quickly understand, master and apply this new technology.
