摘　　要：在传统的汽车造型设计中,对设计方案的改进往往耗时耗力,生产效率因此受到制约。文章介绍了传统造型设计的流程,提出了理想的纯数字化研发流程及基于Alias的曲面造型原理,以某款车为例,对其中的正向汽车造型设计进行了描述,并用showcase软件对其进行渲染。结果表明,Alias直接建模具有灵活性和高精度的特点,Alias在汽车造型设计中的使用对于缩短产品开发周期,保证产品质量具有重大意义。In the traditional automotive modeling design, the improvement of the design scheme is often timeconsuming and needs great effort, the production efficiency is limited. This paper introduces the traditional modeling design process, and puts forward the ideal pure digital research and development process as well as the principle of surface modeling based on Alias. Taking a car as an example, the forward automotive modeling design is described and using showcase software for its rendering is conducted. The result shows that modeling directly with Alias has the characteristics of flexibility and precision. Using Alias in automotive modeling design is of great significance to shorten product development cycle and guarantee the quality of the product.
