Hi Marco!

that's great I can import the pcb-shape correctly and also it is closed 
in 3d-viewer! :)

I also tried with your patch and everything went fine.

Just to complete the 'circle' I tried a generic ellipse generate from 
librecad in R12, but importing it the shape has a little line missing 
and in 3d-viewer will not became closed...

could you please try it and see if it is patchable to import correctly 
the ellipse (dxf r12)?

That will improve the import DXF in pcbnew and may be it could be 
inserted in the stable release...
thank you for your great work!

Maurice
