摘　　要：针对界址点坐标交换格式转换中常出现的点重复、未闭合、区无序等属性与格式问题,基于AutoCAD平台,结合图形对象属性列表元素,采用Visual LISP编程,将图形对象的质量检查与数据生产结合起来,改进了坐标交换格式文件的转换方法。实际结果表明,该方法不仅能避免数据格式排列出错,还能消除因属性错误而衍生的问题,提高了数据质量检查及生产的效率。In order to solve the attribute and format problems in the transformation of boundary point coordinate exchange format, such as point repetition, misclosure, area disorder, etc.,we use Visual LISP to program, and combine the quality inspection of graphic object with data production to improve the transformation method of coordinate exchange format file based on AutoCAD platform. The experimental results show that this method can not only avoid the errors in data format arrangement, but also eliminate the problems caused by attribute errors, while it can improve the efficiency of data quality inspection and production.
