Hello there; When you receive an optional report, the first page lists which elements are insufficient. If you take the column name from here, find the name in the building tree - elements - steel columns section and select it, it will light up in a different color in the model. However, you cannot change the cross-section of only one column for scaffolding. Since the system is modular, a cross-section type is used in a pier. For this reason, you should arrange all sections on the scaffolding on that front. Good work.
