Aiming at the problem that it is difficult to match the actual construction rhythm of aqueduct engineering in the early design stage by relying solely on Revit software for three-dimensional modelling.The Revit software was cus-tomized developed and a forward parametric intelligent modeling method for aqueduct was proposed.It includes three parts:intelligent management platform for forward design of aqueduct,parameterized construction of aqueduct compo-nent model and parameterized modeling of aqueduct reinforcement.The establishment of this method can realize the de-sign and classification management of hydraulic parameters and structural parameters of aqueduct,simplify the complicat-ed modeling steps,shorten the modeling time of designers,and improve the design efficiency.Combined with specific aq-ueduct engineering examples,the accuracy and practicability of the forward parametric intelligent modeling method of aq-ueduct were verified.The work efficiency in the early design stage was significantly improved,which provides a new solu-tion for the promotion and application of BIM forward design in the field of hydraulic engineering.
