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.
