Technical Field
The invention relates to the field of BIM model splitting, in particular to a method for splitting electromechanical embedded parts in any concrete pouring block based on Revit.
Background
With the rapid popularization of Building Information Model (BIM) technology in the field of hydropower construction, the application of the BIM technology is gradually deepened 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 flowing water section, so that the Model needs to be rapidly split and recombined according to the requirements of construction area division in order to be effectively used. At present, a model splitting method provided by Revit software carries out model splitting by utilizing a built-in 'split primitive' function of the software, and has the following defects and limitations:
(1) the function of "splitting primitives" does not apply to the splitting of family instances.
(2) For the splitting of the electromechanical pipeline, the splitting can be carried out only by clicking and selecting with a mouse, the repeated workload is large, and the situations of selection missing and wrong selection can exist.
(3) For the split position clicked by a mouse, randomness exists, and the intersection point of the pipeline on the solid surface of the pouring block cannot be accurately selected.
