This system is aimed to achieve some basic functions of drawing and editing various on this system,the graphics can be drawn and edited on the screen and can be saved as DXF format files in database or memory,so that graphics can be recognized by other DXF format supported CAD software and also can be used as a secondary development. In addition,the system can also read standard DXF format files, using them for secondary development. The main subject of this study is to achieve the drawing,storage,reading and editing of a variety of basic graphics by the GDI+ provided by Microsoft’s C # language and the AutoCAD DXF technology,and all tasks are completed in the VS2005 project is mainly divided into three parts: The first part is to build the system architecture,design the system interface according to the mission statement;The second part is the design of the methods of drawing and edi
