摘要:本文提出一种在图层自动识别算法基础上依据平面图和列表信息创建结构信息模型的方法。利用构件的绘制特征和构件与其标注的匹配算法实现结构构件的自动识别，读取构件列表和楼层标高表信息，匹配平面图的识别信息与列表信息; 通过轴网和楼层高度，获取构件三维坐标系位置; 建立SQLite数据库，存储生成BIM模型所需的数据信息; 采用C#语言和Visual Studio2017开发工具，基于Revit提供的函数库进行二次开发，经实例验证该方法能够快速、准确地实现从CAD图纸到BIM模型的自动转换，从而提高转换的自动化程度和准确度，其转换准确率约为96%。

Abstract: This paper proposes a method to create structural information model based on floor plans and list information based on automatic layer recognition algorithm. The automatic recognition of structural components is realized by using the drawing features of components and the matching algorithm of components and their annotations; read the information of component list and floor elevation table; match the identification information of the plan with the list information; the three-dimensional coordinate system position of components is obtained through axis line and floor height. establish SQLite database to store the data information needed to generate the BIM model; using C# language and Visual Studio 2017 development tools, based on the function library provided by Revit to carry out secondary development. The example proves that this method can quickly and accurately realize the automatic conversion from CAD drawings to BIM model, so as to improve the automation and accuracy of conversion.
