摘　　要：结合某跑车车身外部造型设计,应用CATIA软件进行了正向设计建模,同时也应用手持式三维激光扫描仪及VXelements软件获取了油泥造型的点云数据,进而应用CATIA进行了逆向建模设计,最后通过流体分析软件CFX对其中一种方式获得的三维模型进行了空气动力学分析,完成了造型设计的主要流程,分析了两种方式建模的特点,并提出了造型设计的建议,为车身造型相关专业的学生及设计人员提供参考。The exterior design of the body usually adopts two methods:forward design and reverse design.This article combined the exterior design of a sport car body and applied CATIA software to perform forward design modeling.At the same time,the handheld 3D laser scanner and VX elements software were used to obtain the point cloud data of the sludge modeling.CATIA was used to perform the reverse modeling design.Finally,one of 3D model from them was used for CFD analysis through CFX software,and the main process of modeling design was completed.The characteristics of the two modeling methods were analyzed,and suggestions for modeling design were proposed to provide students and designers of related majors in vehicle modeling.
