SketchUp export for Rhino for rendering

I’m doing a lot more modelling work from a measured survey which I export as a DXF for an architect who uses Rhino and then Twinmotion to render.

So I use nested groups and tags such as

Element_Ceiling, etc.

Element_Ceiling, etc.

and so on.

The architect has asked if I can use ‘layers’ so that it’s easier for their Rhino>Twinmotion workflow so layers something like…

  1. Red brick
  2. Tile roof
  3. White paint
  4. Generic floor layer
  5. Glass
    and so on

Does any have any experience of doing this?
