I am laying out a simple structure. Bearing wall to bearing wall is 35’, with a few non bearing walls between the bearing walls. I will be using a truss to span from bearing wall to bearing wall.; Do I need to model the trusses or are their pre-made trusses with ¼”/1’-0” slope some were online.
For the truss, you could start with a flat truss, such as a Pratt. Then do the sloped roof. Then select the truss and use "Attach top/bottom" "Top" and select the roof. The top of the truss will adquire the slope of the roof.
For the different type of wall above roof level, simply stop the lower wall at roof level, and use a different wall type above the roof.
