User use different software for modelling building depending on how much user-friendly the software is. Now reactions at base level are required to design mat or any footing for which SFA can be used. But since there is no option like in earlier older version to import/ export excel sheet which can help to get section, location of column/ shear wall pier in SFA to carry out further design process. Please look into the same. For building modelling you have to provide user friendly modelling in staad pro connect or give some other solution. Regards
