摘　　要：利用AutoCAD提供的DXF数据交换功能，提出了一种新的生成算法。将空间斜杆一次性生成，直接读取空间杆系结构的有限元分析数据或优化设计数据，自动生成其三维模型图。文末给出了该算法在空间塔式起重机和空间网架、网壳造型中的应用。By utilizing the DXF exchange function of AutoCAD, a new algorithm for generating the 3D model of structure is presented. If can generate a space oblique pole at one time, and by using the finite element analysis original data and the data of optimum design of member structure, 3D modeling were automatically generated with this algorithm. The application of the algorithm in constructing the 3D modeling of the space tower crane and the framework was introduced in the end。
