The invention belongs to the technical field of catenary cantilever assembly, and particularly relates to a construction method for preassembling a catenary cantilever based on Revit, which comprises the following steps: selecting a track center line; selecting an overhead line system model to be pre-configured, and obtaining all family and project parameters of the overhead line system model; modifying measurement parameters, drawing parameters and rule parameters; and according to the modified parameters and constraint conditions of each part in the family file, obtaining an overhead line system pre-configuration model meeting all conditions, and calculating pre-configuration parameters involved in the method to purchase components and perform on-site pre-configuration construction. According to the method, the variable parameters are obtained, the geometric constraint model is established, and the position and size of each construction are calculated through the algorithm, so that whether collision occurs between the components can be found in time, and the problems of reworking and material waste are avoided.
