I am creating a moment frame that requires stiffener plates, as shown in photo. I would normally create beams and column as a weldment and insert that into an assembly so I could then insert the stiffener plates as parts and mate them into place. I am trying to do it all as a weldment so the cut list is clean. Is there a way to copy Base-Flange3 to the other 3 locations it is required or do I have to redraw it and create 3 more sheet metal parts? It won't let me mirror it to the other side of the column.
