A Pro 3d Export to DXF/DWG will keep the layering as in the SKP.
The CAD files layer-colors should match the SKP's layer-colors
The Scene tabs should also come over as Paperspace layout tabs in the DWG...
cheers for those, always good to add a few more materials to the collection.
Just as a tip for next time you psot something, its cool if you can attach a pic of the texture/model so people get an idea of what they're downloading.
