Research On Forward Building Design Based On Open BIM

In recent years,Building Information Modeling(BIM)technology has been widely used in domestic architectural design work,effectively improving the design quality.The advantages brought by BIM forward design are fully recognized in the industry,and the willingness of design units to apply BIM technology is constantly increasing.BIM forward design can give full play to the advantages of BIM technology and play an obvious role in improving the quality and efficiency of building scheme design.Compared with closed BIM,Open BIM has stronger interactivity and better platform compatibility,and can give full play to the advantages of different platforms to meet the increasingly complex architectural design needs.Based on this background,this paper takes the application of open BIM technology in the field of architectural design as the starting point,combined with the technical application in different stages of BIM forward design workflow,and firstly puts forward the view that the application of open BIM technology in forward design will greatly improve the quality and efficiency of architectural design work.Through comparative analysis,the advantages of open BIM over closed BIM are explained,and the necessity of its promotion is demonstrated.Secondly,in the research,through practical operation,the application key points of open BIM technology in the planning and analysis stage of building scheme,scheme design stage,performance analysis and simulation stage and scheme deepening stage are summarized,the technical characteristics and application advantages of open BIM are demonstrated in detail,and the application strategies of open BIM technology are expounded in combination with different stages of design.The advantages of using open BIM technology for positive design are verified,and the open BIM positive design workflow is proposed to prove that it can effectively improve the quality and efficiency of building design,and is in line with the development trend of building industry information in our country.Secondly,GDL computer programming language is used to design BIM component library,which shows the role of computer language in open BIM workflow and demonstrates the process of computer program writing in detail,and then demonstrates the positive role of computer language in the construction of BIM component library,and puts forward a technology combination strategy combining computer programming language and architectural design.Finally,the application of open BIM technology in architectural scheme design is demonstrated in detail through practical cases to verify the technical feasibility and advantages of high efficiency,high quality and high interaction,and the forward architectural design process based on open BIM is obtained.At last,the research achievements and shortcomings of this paper are summarized,and the future development trend is forecasted.It provides some reference for the follow-up research work.
