Application Study Of Dynamo On Construction Information Management

Building Information Modeling Technology is developing rapidly in the field of construction information management in our country.However,because of the absence of convenient information management function,high difficulty in application and high learning cost,ordinary engineers are hard to use BIM effectively in construction project.In order to solve these problems,this paper proposes a solution to independently develop information management function by using visual programming platform Dynamo.Dynamo,the latest programming software developed by Autodesk,usually works on Revit.Users just need to connect the predefined function nodes in the workspace for a problem,and the problem can be solved by the set of progressive stream.Because of Dynamo,the function of the BIM software can be greatly expanded.In order to verify the feasibility and effectiveness of the scheme,the following three aspects are studied:(1)Comparative study of Dynamo and RevitAPI for development information management function.By making experiments,this paper compares the similarities and differences between Dynamo and RevitAPI,and found that Creating program by Dynamo can spend less time and energy and lower learning cost than RevitAPI,but the program by Dynamo have poorer UI and transitivity than RevitAPI.Moreover,This paper point out that Dynamo is suitable for nonprofessional developers who need to make programs to solve the current problems quickly.Because the transitivity of Dynamo program is not ideal,it is more suitable for the situation that the creator is also the user.(2)Application study of Dynamo in construction information management.By analyzing the construction information management model based on BIM,this paper obtains the location and the application method of Dynamo in engineering information management.This method can be briefly described as: requirement analysis--program design--cutting module--create node group--debug release program.(3)The practical application of Dynamo in construction information management.This paper takes a curtain wall construction project in Chongqing as an example.By analyzing the challenges of project,the information management scheme based on BIM and Dynamo is proposed.The corresponding Dynamo program is developed for the supply chain information management and site construction simulation of the component,and the application effect in the actual project is demonstrated.The results of this study can effectively solve the problem of BIM using in the process of engineering information management.It provides technical support for the application and popularization of BIM technology in the field of engineering information management.In addition,the applicability analysis and program development of this research on the visual programming platform Dynamo can provide effective reference for the future Dynamo application.
