When exporting a pln file to dwg, I have an issue with complex structures, walls in particular. The layers of a composite wall are exported as hatches. There no lines showing the individual layers of the wall. Whether the walls are exploded or sent as blocks from Archicad, no separation lines appear in Autocad. When working in Autocad, some of these lines are needed as a reference. Any way to achieve this? I don't really want to change the way the walls are modeled in Archicad.
