摘　　要：对AutoCAD的dwg、dxf图形文件格式进行深入分析 ,通过Access建立数据库对图形进行存储。利用VisualC + +语言开发应用程序 ,通过ODBC接口访问图形数据库 ,可以方便地对图形数据库进行浏览、修改、查询 ,同时可对图形进行增加、删除 ,并且能够对图形进行预览、放大、缩小。The format of AutoCAD graphics files including dwg and dxf have been thoroughly analyzed and the database of Access have been established to store graphics. Exploitating application by using Visual C ++ language and having access to graphics database through the fetch of ODBC,consequently we can not only expediently look through、modify and look for the graphics, but also can put new graphics into database and delete old ones. At the same time, It is important for user to preview、zoom out、zoom in and move graphics and so on.
