摘要
本文介绍了AutoCAD-AME实体造型的特点及其图形交换文件DXF的文件格式,通过对AutoCAD三维实体造型的实体几何信息和拓扑信息的提取与转换,利用二叉树结构实现了有限差分网格的自动剖分,并给出了相应的计算机流程。
The feature of Auto CAD AME solid modeling and the file format of drawing exchange file (DXF) have been presented in this paper.Through fetching and converting the geometric and topological information of 3D solid model constructed with Auto CAD AME modler,automatic enmeshment of Finite difference was realized via binary tree.Besides,the corresponding computer flowchart has been also given.
