Re: pursantaj problem If the beams droop 25/50 in the area where the k27 beam is located, the problem is solved. There are only problems with the basement curtain. P1,2,3 curtains need to be combined. Also, the basement curtains must be sub-floor / mark the icon that does not continue on the upper floors. In the analysis settings, you can make the R floor number 7 analysis.
