Re: RED COMBINATION Hello; Combination currently works to produce only symmetrical models. That's why you can't just remove the top section. You have to intervene during the drawings. The ridge joint is for column-beam inclined connections in the program. If you use the Butt Plate Beam joint joint between two beams as in your model, you still need to do symmetrical modeling and you can also get the joint design report. The design of the ridge joint is not done. Note taken for editing. Good work.
