Background
Along with the rapid popularization of the building information model (Building Information Model, BIM) technology in the field of hydropower construction, the application of the technology gradually goes deep from a design stage to a construction stage, but the BIM model designed in the design stage is usually not subjected to pre-splitting and recombination according to a construction flow section, so that the model needs to be rapidly split and recombined according to the requirement of construction region division for effective use. At present, the model splitting method provided by the Revit software utilizes a built-in "split primitive" function of the software to split the model, and has the following disadvantages and limitations:

(2) For the splitting of the electromechanical pipeline, only the mouse point selection can be used for splitting, the repeated workload is large, and the condition of miss selection and miss selection possibly exists.
(3) For the splitting position of the mouse point selection, randomness exists, and the intersection point of the pipeline on the entity surface of the pouring block cannot be accurately selected.
