摘　　要：三维设计技术是当前计算机辅助设计技术的发展趋势,其中三维建模是三维设计技术的基础。本文根据长江大桥工程实例的建模实践,介绍了一种适用于大型桥梁结构特点、基于CATIA骨架和模板的三维建模方法。该方法符合实际工程设计习惯,可推广应用到各类大型桥梁工程。3D design technology is the current trend of CAD techniques, of which 3D modeling is the basis. According to the modeling practice in Yangtze River Bridge Project, this paper describes a 3D modeling method based on CATIA skeletons and templates, which is applicable to the structural characteristics of large bridge. The described method conforms to normal engineering design approach, and can be applied to all kinds of large bridge engineering project.
