It seems like nobody on Youtube is drawing truss and frame roofing as we make houses here in
New Zealand.
Another thing is it seems all Revit projects start with the walls. In real life it starts with the site.
Luckily on this project (already built from 2D Autocad drawings) I had access to the surveyors drawings which even had the contours in 3D ready to go.
Interestingly, this import showed the ground levels were slightly out as far as the original drawings were showing. Score One for Revit.
After an unnecessary diversion into Autocad Architecture to use the Drape command and then bringing that into Revit and finding that was not a lot of fun, I used the button marked "Create from Import", and this seemed to work OK.
It seems Revit is so simple to use in the ordinary tasks such as inserting walls doors and windows, but agonisingly difficult in the complicated bits- eg inserting beam systems. I guess even they will feel straightforward after much use. Getting the right level or even reference plane is sometimes like a blind man in an unfamiliar room. Nobody else seems to have these problems.
Still, they might have had proper training!
One little feature I found really cool is if you click on a roof, it becomes transparent, showing the structure below.
