Hi Michael,
that would work just fine.
But I tried running it with some very simple files (1 rectangle for example) and the files are coming in empty...

If I open the DXF in Rhino it works fine.
If I open the DXF in modo or cinema4d, there is nothing showing.
(If I save the dxf in rhino and open it again in modo or C4d, it comes in fine).

Do you know what this could be?
thanks,
