Lightweight Analysis of Expressway Model Based on Revit Software
With the promotion and popularization of BIM technology,more and more production links in the construction industry have adopted BIM technology.However,at present,the huge data of BIM model has seriously hindered the application of BIM technology in information storage and transmission interaction.Therefore,it is necessary to study the lightweight of BIM model.Through the expres-sion of model data and geometric information established by Revit software,the model lightweight can be realized by saving the single class model data and the spatial transformation matrix of a single model and establishing the reference relationship.Export and load the converted data to restore the model verification reference method can reduce the file size by 40%while maintaining model fidelity,but it takes a long time to export the model.The research results show that the lightweight application of BIM model can greatly reduce the terminal equipment configuration and network bandwidth requirements of the construction management system,save the system deploy-ment cost,improve the use efficiency of the system,and ensure the efficient and stable operation of the system.
