RESEARCH ON GRAPHIC CONVERSION METHOD AND PROGRAM IMPLEMENTATION BASED ON DXF FILE
基于DXF文件的图件转换方法研究及程序实现

Through the research for the rules of storing entity data in the DXF,achieving that the direct operating of DXF file to complete maps conversion without the CAD support is achieved and the corresponding graphics conversion program has been compiled with specific projects.After test,with this program we can complete map conversion between National Coordinates,National Coordinate and Local Coordinate,Local Coordinates,and we have achieved integrated blocks conversion in the conversion process.
