汽车外表面建模(A级曲面)是汽车造型最终确定,同时又是车身结构设计的开始,对于整个车身的设计具有决定性的作用,而在外表面建模过程中,曲面分块即主体面的确定,是车身外表面Class-A曲面造型的核心,本文阐述在使用CATIA外表面建模的过程中,说明主体面确定的重要性,并以某微车前翼子板的建模为例将改进前后的情况对比具体化。
Automotive exterior surface modeling (A-level surface) is the final vehicle shape determination, but also the beginning of the body structure design for the entire body design has a decisive role in the modeling of the outer surface, the surface sub-block that is the main surface Determine the core of the Class-A surface shape of the outer surface of the car body, this paper describes the use of CATIA outer surface modeling process, indicating the importance of determining the main face, and a micro-car front fender modeling as an example Improve the situation before and after contrast specific.
