This paper focuses on the development of steel tubular scaffold with couplers in construction, based on Revit, through the aid of Revit API. The specific method is to create required family members of the scaffold by using C# as the programming language. Revit API can automate the rivial modeling of scaffold, which can assist the designers to build the moulding in short time, and meanwhile integrate the computing functions of scaffold into Revit. This program finally achieves the functions of scaffold safety calculation and intelligent modeling. Moreover, taking a specific instance to illustrate the stability and applicability of this method, this program can realize a 3D visualization model of scaffold in a short time, which satisfies the engineering requirement and provides rich engineering information. Finally, it significantly improves the work efficiency of the designers and constructors.
