All of the steel profiles come back to their original state when I make any joint object and delete it if I don't like it. However, when I do this between any steel object and the column (for example: when I connect a BA column and a truss with a Bracket), the reinforced concrete column gets trimmed a little with the effect of the plates. When I delete these plates later, the column does not return to its former height. In addition, when I use this combination on a 30x300 cm curtain top, a 300 cm long plate is thrown and I can only enlarge this plate and cannot make any reduction.
