| At present,most architectural design enterprises are still managed mainly in the form of paper drawings and documents,which is easy to lead to problems such as low design efficiency,poor design quality,information silo,etc.Architectural design enterprises are facing the dilemma of Digital transformation and upgrading.BIM technology has the advantages of coordination,visualization and parameterization,which provides support for Digital transformation and upgrading of architectural design enterprises.The development and application of BIM technology cannot be separated from the support of BIM software.However,BIM software has the disadvantages of poor cross platform performance and high requirements for computer software and hardware environment configuration.With the gradual maturity of WebGL technology,it has good cross platform and portability,providing support for BIM model 3D visualization on the WEB side.Therefore,this article combines BIM technology,WebGL technology,and collaborative design concepts to develop a web-based BIM collaborative design platform,thereby shifting traditional 2D design to 3D model digital design and expanding the data-driven and information-based approach to collaborative design.The main research work and achievements of this article are as follows:(1)Research on data generation of drawings and models and collaborative design based on WEB.Using SVG 2D vector graphics format and Three.js 3D rendering engine and other technologies,this thesis studies the data generation and collaborative design of drawings and models on the Web side from multiple perspectives and methods,and puts forward three feasible schemes.One is the original interactive model design based on the Web side,the other is the data driven model collaborative design based on the Web side,and the third is the lightweight collaborative design based on the BIM model on the Web side,Laying a core foundation for platform development.(2)Research on File Informatization Collaborative Management Based on WEB.Based on the characteristics of file management and the basic requirements of file collaboration,a web-based BIM collaborative design information management system has been developed.Basic functional modules including project workbench,document management,document collaboration,personnel management,and collaborative message viewing have been developed,achieving multi-party file collaboration and information sharing during the design phase,providing basic functions for platform development.(3)Research on front-end and back-end development of the platform.The front-end and back-end development technologies such as VUE front-end framework,Echarts visual chart library,Node.js Express framework and MYSQL database are applied to realize the data generation and collaborative design of drawings and models based on the WEB side.The front-end page development and back-end server development of the web-based file information collaborative management system have completed the overall research and development of the platform.(4)Research on the Application of Platform Structure Collaborative Design.By using Yingjianko structural analysis software and combining with engineering examples,the second solution for model data generation on the WEB side-data-driven modeling solution-was used to transplant Yingjianko models and structural calculation results to the WEB side,achieving visual display of component level structural calculation results on the WEB side,and achieving the application of platform structural collaborative design. |
