摘要:BIM技术中面向电气设计的应用研究相对较少，针对这种情况，以国内外广泛使用的Revit软件为基础，构建基于BIM的电气设备族平台。对电气设备参数化信息模型进行了研究，利用Revit API外部功能扩展方式，实现Revit对象的访问、过滤、编辑与创建，利用Family API实现电气设备族类型获取、族创建和族编辑，结合SQL Server，对Revit模型元素实现基于关系数据库的数据存储，该平台实现电气设备族统计、电气设备拖动和族属性导入。通过实际案例，验证平台的可行性与可靠性。

Abstract: Electrical design oriented application research in BIM technology is relatively little, for this kind of situation, on the basis of Revit which is widely used at home and abroad, we built electrical equipment based on BIM platform. After studying parametric information model of electrical equipment, we used expansion method of Revit external API function and achieved the access of Revit objects, filtered, edited and created with Revit objects. We achieved the access of electrical equipment types, edited and created with Family API. Combined with SQL server, we realized Revit model elements data storage based on relational database. This platform can realise electrical equipment group, electrical equipment drag and importing family attributes. Through the actual case, the feasibility and reliability of the platform are verified.
