| With the rapid development of intelligent transportation,unmanned driving and other new technologies,the information technology revolution in the field of traffic engineering has come quietly.BIM(Building Information Model),as a new technology to express graphic information,is being used in all aspects of the whole life cycle management of traffic engineering projects.Although BIM Technology has been applied in the field of transportation for more than ten years,there are still many unsolved problems,among which the efficiency of modeling software is one of the reasons for its slow development in recent years.Autodesk platform is one of the most popular solutions in BIM modeling stage.In order to explore the application of“revit+dynamo” in the parametric layout of bridges,the paper proposes to improve the efficiency,professionalism,accuracy and ease of learning of the bridge modeling solution through the secondary development of dynamo platform.Through the research on the basic technology of dynamo,the technical feasibility of realizing the rapid modeling of bridge by dynamo secondary development is proved from the gene of the platform bottom layer;through the research of unified mathematical model theory of pile coordinate calculation in the line,the feasibility of theory is proved,and a set of bridge rapid modeling function nodes are finally opened and the core nodes are carried out with the project case Precision analysis,meet the production demand.Based on the developed function node of bridge rapid modeling,the paper simply introduces the parametric layout method of common highway bridge model,and successfully creates a BIM model of highway bridge.The new development direction and technical case are provided for the quick modeling solution of "revit+dynamo" bridge.This bridge modeling scheme based on visual programming technology also provides reference for the architecture design of domestic bridge modeling platform. |
