摘　　要：BIM技术是建筑产业信息化的关键性技术,Revit以其提供丰富的二次开发API等特点,在市场中占有绝对优势。在浏览器中展示Revit三维模型有利于开发公司对于项目的设计、施工、运维等的掌控,因此该方向的研究对建筑行业很有意义。文章通过对Revit API的解析与二次开发进行研究,实现将三维建筑模型的几何模型与数据模型的分离,将数据模型存储于MySQL数据库,几何模型存储为JSON文件,在Web端使用Three.js对JSON文件解析渲染,从而在浏览器端实现三维模型的重建。BIM Technology is the key technology of construction industry informatization.With its rich secondary development API and other characteristics,Revit has an absolute advantage in the market.Displaying the 3D model of Revit in the browser is conducive to the development company’s control over the design,construction,operation and maintenance of the project,so the research in this direction is of great significance to the construction industry.Through the research on the analysis and secondary development of the Revit API,the geometric model and data model of 3D building model are separated.The data model is stored in MySQL database,and the geometric model is stored as JSON file,which is used on the Web Three.js by parsing and rendering the JSON file,the 3D model can be reconstructed in the browser.
