[0002] Building Information Modeling (BIM) is an integrated digital building design and construction management method. It is based on three-dimensional digital technology and integrates all information from the building design, construction and operation stages by creating a virtual building model. The BIM model is a digital expression of the entity and functional characteristics of the project facilities. BIM engineers are responsible for maintaining and updating this building information model to ensure its accuracy and completeness. BIM technology has been widely used in the field of construction and civil engineering, especially in the construction stage, where BIM technology has achieved multi-dimensional and multi-angle applications. In order to ensure the degree of informatization application of BIM technology in the construction stage and that the BIM model can be updated in a timely and effective manner as the drawings change, it is necessary to realize the automatic update of the BIM model. Therefore, an automatic update method for civil engineering BIM models came into being.

This form not only increases the workload of modelers, but also complicates the update process of BIM models. Frequent changes in drawings result in numerous versions of model updates, which easily causes confusion in model management applications. Summary of the invention
