摘　　要：在AutoCAD 2000作图过程中利用面域的特性对加工图纸进行处理并保存为DXF文件,再利用Visual C++6.0编程打开DXF格式保存的这样的图形文件,将面域以专门的数据结构存储,进一步优化后可以应用到各类工程领域。该文研究DXF文件中面域实体的数据提取算法,给出了针对单个面域的优化处理算法,并应用到激光切割过程中的数据输出,减少了空走行程。In the processing of drawing with AutoCAD 2000, the property of region could be used to edit the drawing paper and to save it as a DXF format file, then make a program by Visual C＋＋6.0 to open this graphic file, and save the data in a particular data structure, finally the data is put to use in each engineering area after it had been optimized well. The paper researches how to read the data of region in a file of DXF format, produce an optimized method to the entities in a region, which is used in output data to the laser cutting and to reduce the empty moving path.
