I'm very new to Revit Structure and am stuck something I hope is very simple. I have 6x6 angles on top of a square 8" CMU wall structure...these angles are the boundary for the floor deck and concrete topping above. The question is, how do I manage the corners where these angles come together? I found the beam/column join tool, but it seems only to allow for 1 angle or the other to occupy the corner, not both. Can these be mitered together? Or if 1 angle goes clear to the corner, can the other one be cut to fit?
