| 摘 要： | 提出了进行AutoCAD数据坐标系统转换的新方案。该方案利用AutoCAD数据区域内的、在两个不同坐标系统中的公共点坐标值,求得该区域的七参数,然后在Visual Stutio环境中,加载AutoCAD提供的类库,利用七参数解求图形在新坐标系统中的坐标串,形成一个新的AutoCAD数据文件。本方案操作简便,转换效率高,精度好。

| Abstract: | This paper puts forward a new scheme of converting AutoCAD＇ s Data Coordinate System. This seheme utilizes the coordinate value of common points from lwo different coordinate systems in AutoCAD＇ s data area to obtain the area＇ s 7 parameters. Afterward,it loads class libraries afforded by AutoCAD and get graphics＇ coordinate strings in new coordinate system by using 7 parameters,then forms a new AutoCAD＇ s data file. This scheme operations easily and have a high efficiency and precision. |
