Please, I really need the DXF format to export layers (styles).
Because: if I export MoI > AI it has layers, then ok, I convert from AI > DXF\DWG, and import into AutoCAD. The imported drawing is not precise. It has slightly overlapping lines and makes it impossible to hatch.
If I export MoI > DXF and import in AutoCAD, the lines are perfect. But no layers. :(
