I am trying to export my floor plan to dwg file and I have curtain wall there which have panels as regular wall types. The problem is that exporting it will put those panels on the wall layer. I need them to be on curtain wall panel layer. I tried to use "Function" parameter in wall family by changing certain wall types to Retaining (since I don't use this parameter) and changed Wall/Retaining category layer to curtain panel in dwg export setup. But it seems it has no effect.
I also noticed that walls inserted as panels into curtain wall do have a parameter under "Identity Data" with the name "Categorize as" where are two values - wall or panel. But this does not have any effect either since there is no category for it in export setup.
I don't see an automatic solution for this. The only alternative I can think of is to make 2 exports, one for the curtain walls, and another one for the rest of the floor plan. In the first export, change the settings for Wall to be "A-Curt-Wall-Panel", and in the second export, change the settings for walls back to "A-Wall". Then, in AutoCAD, merge the two exported dwgs. into one.
Actually I came to this conclusion too But works for me right now. But as you said, not a solution though, but workaround.
