摘要:将有限元网格划分的栅格法的思想和算法运用于任意多边形平板网架的快速建模中，在PKPM的SPASCAD空间建模软件上通过编程实现了:当指定任意多边形的边界点，以及网格排列方向时，程序自动生成以四角锥及三角锥为基本单元的平板网架模型。该程序大大提高了这类网架模型的设计效率，并为以后复杂异形网架的快速建模提供初步探索。
Abstract: In this paper, Grid Method, which is usually used in finite element mesh generation, is now applied for rapid modeling of arbitrary polygon Grid Structure, and it's function is realized in SPASCAD (the software of space modeling)by the developing of program. The engineer only selects the beginning edges of polygons and determines orientation of Grid.The software can automatic forming the model of plate space frame.The basic element of plate space frame includes Square pyramid and Triangular pyramid. The software can greatly improve the engineer's efficiency, This work just is preliminary research for the Rapid modeling of irregular grids, structures, and more development is needed to be continue.
