An automatic update method for civil bim model

Abstract

The invention provides an automatic updating method of a civil engineering BIM model. The method comprises the steps of establishing the original BIM civil engineering model, and conducting componentcoding; importing a CAD update drawing for updating the model, and adopting Revcloud to mark out an area to be changed; identifying and revising the Revcloud and the area to be changed; extracting drawing information of the area to be changed, and converting the drawing information into a three-dimensional solid component with a specific code; modifying the specific code of the three-dimensional solid component into a code same as the code of a component of a corresponding part in the original BIM civil engineering model; by replacing the component in the original BIM civil engineering model with the component with the same code, completing automatic updating of the original BIM civil engineering model. The method has the function of automatically updating the BIM model, overall remodelingof the civil engineering BIM model is not needed, the manpower cost can be significantly saved, and the use efficiency of the BIM model is improved.

Description

technical field [0001] The invention relates to the field of construction and civil engineering informatization, in particular to an automatic updating method of a civil engineering BIM model. Background technique [0002] With the development of information technology, BIM technology in the field of construction and civil engineering has been widely used, especially in the construction stage of BIM technology to achieve multi-dimensional and multi-angle applications. In order to ensure the informatization application of BIM technology in the construction stage and the BIM model can be updated in a timely and effective manner with the change of drawings, it is necessary to realize the automatic update of the BIM model. [0003] In particular, large and complex commercial complex super high-rise buildings have many specialties, complex drawings, frequent changes, and the mode of designing, changing, and constructing simultaneously, resulting in frequent changes to the BIM mod...

[0003] In particular, large and complex commercial complex super high-rise buildings have many specialties, complex drawings, frequent changes, and the mode of designing, changing, and constructing simultaneously, resulting in frequent changes to the BIM model

This form not only increases the workload of the modeler, but frequent drawing changes make the model update many versions, which is likely to cause confusion in the model management application
