Press the OK button and then press Ctrl+q to update the sheet size. Then apply a view of the part and place it in the upper left corner. The drawing can only contain solid lines, so remove all the centerlines and construction lines from the drawing. Make sure that the view and sheet scale are 1:1 scale. Check over the drawing that it contains all the cuts you want to make, all the solid lines represents a cut. Then press Ctrl+q again and save the drawing as a dxf file.
