Development of CAD dynamic interaction system forgravity dam based on 3D design
基于重力坝三维设计的CAD动态交互系统开发

In order to make a design scheme reasonably and fast, as well as reduce the design cycle and cost in the feasibility study stage of gravity dam, this paper developed a 3D-CAD dynamic interaction design system with VB 6. 0, based on the limit state design method. The system would produce 3D parametric models of gravity dam and fulfill the structural analysis. Data exchange would happen between the system and AutoCAD by dynamic interaction during the analytical process, which achieved the goal of accurate and fast dam design. In practice it has proved that the system greatly improves the efficiency of the section design and is practical strong. In brief, the system has a great significance to gravity dam design scheme selection in the feasibility study stage.
