Description
Technical Field

Background
Currently, BIM technology has been widely applied to a number of fields such as construction, environmental protection, fire protection, traffic, mapping, geographical information, digital cities, etc. In these applications, building models play a vital role. However, the BIM model carries more data information, the model is huge, and the data volume of a single building model is usually in the level of hundred megabytes. If thousands of such models are to be loaded in a city level scene, the system will become abnormally stuck. Therefore, some method is needed to lighten the BIM model.
At present, revit is taken as a common BIM modeling software, and occupies a great proportion in the market, and more than 80% of BIM models are produced by Revit. To facilitate secondary development, revit provides a corresponding API. Based on the Revit API, a series of operations such as data filtering, component extraction, document editing and the like can be performed on the BIM model, so that the possibility is provided for the light weight of the BIM model. Compared with other light-weight methods (such as BIM model light-weight based on IFC file), the method can operate the model based on the software interface, avoid data loss caused by the fact that the model is exported as an intermediate file such as IFC, and enable the operated model and the original model not to generate corresponding deviation.
