Nowadays, with the limitations of tranmission softwares unable to transmit models from Revit into computing softwares accurately and efficiently, the efficiency of structural design is reduced significantly when adopting BIM design. Based on the frane and bent structure of thermal power plant building.this paper analyses the design flow and functional features of Revit, put forward a new solution of linking up Revit 2016 and STAAD.Pro, and proposes suggestions for perfection in Revit.
