+Circle object, Arc object, Line object and Polyline object are supported. Other kind of objects in DXF file are ignored when translating to gerber data.
+
+You can specify line width (default 0). PCB tools extension will translate DXF primitive shape to RX-274x line or arc sequense using circle aperture with diamater as same as specified line width.<br>
+
+```python
+import gerberex
+
+dxf = gerberex.read('outline.dxf')
+dxf.to_inch()
+dxf.width = 0.004
+dxf.write('outline.gml')
+```
+
+You can also translate DXF closed shape such as circle to RX-274x polygon fill sequence.<br>
+In order to fill closed shape, ```DM_FILL``` has to be set to ```drawing_mode``` property. In this mode, All object except circle and closed polyline will be ignored.<br>
+
+```python
+import gerberex
+
+dxf = gerberex.read('outline.dxf')
+dxf.draw_mode = gerberex.DxfFile.DM_FILL
+dxf.write('outline.gml')
+```
