摘要
CAD系统之间的数据交换是三维CAD系统的重要组成部分,也是难点问题。本文重点对国产三维CAD系统在与其它典型商用CAD系统进行数据转换过程中出现的拓扑异构、几何间隙等问题进行了研究,并给出了相应的解决方法。这些方法已被成功地应用于三维数据转换接口的开发中,并取得了较好的实用效果。
The data transfer between different CAD systems is an important part of 3D CAD system, and also a difficulty. This paper focuses on the research on heterogeneous topology and geometrical tolerance occurring during the process of data transfer between domestic 3D CAD systems and other typical commercial CAD systems, and their relevant solution is given. These methods have been successfully used in the development of data transfer interfaces, and proves to be effective.
