I am trying to make a frame that looks pretty much like a cube. I want to keep the position and the way they are welded the same, but that's when the problem occures. The trimmed angle beams are only trimmed where they touch the vertical beam. The last bit of the inside of the corner is not trimmed. In real life you would not be able to make it that way. Is there anyway to fix this problem in the way that the beam is just completly cut off straight when it hits the vertical beam?
