Hello, we are trying to learn the demo version, when we want to select the reinforcement in the beam reinforced concrete section, no matter how much we increase the number of reinforcements, we do not receive a price warning (but if we repeat the analysis, we get a purchase warning, this control does not take place interactively during the selection of the reinforcement), besides, we do not get a warning whether the reinforcement fits into the cross section or not. There is no warning, we did not see the possibility of placing the support reinforcements in the second row in the section, as if all the reinforcements are placed in the same row.
