基于AutoCAD的DXF格式文件读写方法研究

DXF格式文件是传统图形开发中最常用的图形交换格式之一，它逐渐发展成为一种国际通用图形格式。文章阐述了DXF格式文件各段组码的含义，对现有的一些DXF读写方法进行了简单的分析，提出了一种可行的DXF文件读取方法，该方法主要是在读取方法上进行了一些相关的改进，并绘制图形进行测试，以求达到比较好的效果，满足科研的需要和现实生活中的一些应用，最后讨论简单图形的保存方法。

Research on Read and Write Method of DXF Format File Based on AutoCAD

The DXF format file is one of the most popular graphics exchange format in traditional graphics development. It becomes an international graphics format gradually. The paper expounds meanings of each section＇s groupcode of DXF format file, and analyses the existing DXF read and write methods. It puts forward a feasible read method of DXF file. This paper presents some associated improvements in read method, and drawing graphics for test in order to obtain a better effect and satisfy the need of research and some applications of the real life. Finally the saving method of simple graphics is discussed.
