The invention discloses a pile foundation model creation method based on Dynamo and Revit. The pile foundation model creation method comprises the following steps that S1, making a pile-by-pile coordinate file of a bridge center line and a data file of a pile foundation according to design requirements; S2, in Dynamo, fitting by using the pile-by-pile coordinate file of the bridge center line in S1 to generate a three-dimensional curve and a two-dimensional horizontal curve; S3, according to the data file of the pile foundation in the step S1, obtaining a normal plane at the corresponding mileage of the two-dimensional horizontal curve in the step S2, and offsetting the normal plane to obtain a group of planes which are called as plane groups; S4, according to the data file of the pile foundation in the step S1, generating a straight line at the corresponding mileage of the two-dimensional horizontal curve in the step S2 along the tangential direction, and offsetting the straight lineto obtain a group of straight lines called as a straight line group; S5, intersecting the plane group in S3 with the straight line group in S4 to generate an intersection point; S6, manufacturing a parameterized pile family, placing the pile family in Revit according to the data file of the pile foundation in S1 and the intersection point in S5, and obtaining a final pile foundation model.
