A method for establishing a bridge BIM model by adopting Dynamo software

Abstract

The invention relates to a method for establishing a bridge BIM model by adopting Dynamo software, which belongs to the technical field of BIM models and mainly comprises the following steps of processing a pile foundation coordinate table provided by a design unit to obtain relative coordinates; reading the pile foundation coordinate table by adopting Dynamo to establish a bridge route; placing abridge pile foundation, a bearing platform, a tie beam, a pier column, a cover beam and a support according to the relation between each pile number and the central pile number coordinate table; adjusting elevation parameters of each component according to the data in the bridge pier feature elevation list in the drawing; placing a box girder, a wet joint, bridge deck pavement and a guardrail, and adopting the Dynamo software to complete the modification of elevation parameters of the box girder, the wet joint, the bridge deck pavement and the guardrail; and rapidly obtaining and restoring the relative coordinates of the pile foundation in Revit into real coordinates, and conducting the error comparison on the real coordinates and pile foundation XY coordinates provided in a constructiondrawing. The method can effectively solve the problem that a traditional method cannot determine a bridge engineering route which is long in route and interrupted in the middle.

Description

technical field [0001] The invention belongs to the technical field of BIM models, and in particular relates to a method for establishing a bridge BIM model by using Dynamo software. Background technique [0002] BIM Building Information Modeling (Building Information Modeling) or Building Information Management (Building Information Management) or Building Information Manufacturing (Building Information Manufacturing) is based on various relevant information data of construction projects, and simulates the characteristics of buildings through digital information simulation. The real information of real information, through the three-dimensional building model, realize the functions of project supervision, property management, equipment management, digital processing, engineering management and so on. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. T...
