Have a nice day; the raft says the reinforcement is insufficient, but when I get a report from the optional reports, the report can be output..So it gives the report directly without the error table? is this normal? I had one more question; When the reinforcement on the raft is insufficient, when I do not make a superstructure interactive solution, the raft reinforcement can come out without errors, I could not see much difference in the report or the quantity, what kind of problems may occur in the solution without superstructure interaction? thanks..
