The DXF and DWG file formats also support arcs and circles, which you can approximate in your output formats by creating multiple small line segments approximating the circle or arc.
DXF和DWG文件格式还支持弧和圆，您可以在输出格式中通过创建多个小线段来近似模拟圆或弧。
As such, more applications support it than support DWG, and the file format specification is published (see Resources for a link to the full DXF specification).
正因如此，相比dwg，这个格式在更多应用程中受到支持，并且相关的规范也已发布(参阅参考资料获得完整d XF规范的链接)。
