I am trying to create a roof frame that has sloped W12 rafters with W8 "legs" that are about 4' tall. I can put the rafters in as beams and create a work plane to slope them and they will miter nicely at the ridge. But I only know how to put the W8 legs in as columns and then Revit will not miter the W12's and W8's. Is there a way to put in a vertical element as a beam?

Thank you.
