摘　　要：提出了使用 VBA和面向对象的思想 ,在 Auto CAD上开发有限元网格划分程序的方法。本程序通过平铺法实现自动三角形网格划分 ,并可以用两种方法把三角形网格转化为四边形网格 :合并法和分割法。文中详细分析了 VBA面向对象的数据组织方法。实践证明VBA是一种方便、快捷。This paper presents a new method for developing CAE program using VBA on AutoCAD platform. By using the method of tiling mesh, this program can automatically generate triangle meshes. This program can also transform triangle meshes into quadrilateral meshes by using the following two methods: one is merging two triangles into one quadrangle, the other is dividing one triangle into three quadrangles. Additionally, the idea of object-oriented data organization is adopted in the program. Finally, the method is validated by a practical example.
