Do Structural Walls and Slabs belong in the Struc model or Arch model? I know BIM ethos would say that they are owned by Structural but what about inserting Wall Hosted elements in the Arch model such as Windows and Doors. And slabs? I would also like to not have to duplicate elements in both models and then have to create filters to remove elements which already exist in the other model from takeoffs, shedules.

Thanks
