Hello, My Suggestions: --Check the building coordinates and other information from the wizard where the building will be built, --Remove the short tie beams in the dilatation, --Fix the errors in the geometry control, (there are columns that do not overlap S68) --Reduce the moving load if you are not going to use the attic floor, - -It would be better to increase the width of the narrow sides of the column, which has a height of 5m and does not have floor interconnections, (like S16-S17) --Enter the wall weights at 2.5m elevation, --Fix the column (B) errors, --The suggestion is in the basic appendix.
