I have not found a clean way to build a roof with TJI interior structure w/ exposed back span exterior rafters (see attached autocad detail I am trying to build in revit). I have tried to build the interior roof structure as one roof and the exterior roof structure as another but when I do this I can not trim my walls as the siding is under the outer roof and the structure of the wall in under the inner roof. Also this takes a lot of time and does not work well for changes. Any ideas?6-08 Model (1).pdf
