In the example below I have a very basic roof plan which I need to setout my roof framing plan on. I could very simply go through and show my intended framing with some basic 2D lifework, however, if I am interested in maintaining my 3D model, then there is another way to go. Select
If you are modelling rafters using the Beam Tool, changing the profile to a complex profile allows a rotation angle as well as a pitch. Handy if your beams are running against or with the slope of the roof as in the case of rafter purlins.
