二维图形加工软件，读取dxf文件实现图形加工，并输出加工代码-Two-dimensional graphics processing software, read the dxf file realize graphics processing, and output processing code

CAD文件dxf格式转化为G代码的软件，非常好用，而且源码开源的，可以作为学习参考的例子-Dxf format CAD file into a G-source software, very easy to use, and the source code open-source can serve as a useful example to study
