With the rapid development of information technology, the construction industry has gradually realized that the traditional two-dimensional design and construction methods can no longer meet the needs of complex projects. BIM, an integrated approach to design and management, is revolutionizing the construction industry through digital modeling, collaboration and information sharing. In this context, Revit has become one of the representative software in the field of BIM with its powerful functions and ease of use. Taking revit as an example, after a series of building prototype modeling experiments, ifc files exported from revit model are further transformed into graphic data structures, and the constructed BIM semantic graph is compared and analyzed, so as to understand revit from the perspective of the graph and enable it to organize and transmit information more comprehensively and reasonably, thus helping to build BIM information semantic graph. Facilitate the sharing and exchange of information.
