The building information model (Building Information Modeling, abbreviated as BIM) technology is applied as a high-efficiency collaborative tool in the design and construction of building engineering projects, and the essence of BIM application is that model data can continuously play a role in the construction and later operation management of the projects throughout the whole life of the projects.
In the building design process, the design of the vertical face is taken as an indispensable part, and the diversity of the vertical face modeling and the richness of the materials of the outer vertical face are a great difficulty in the forward design of the building.
