Description
Technical Field
The invention relates to the technical field of BIM, in particular to: a BIM model lightweight method based on scene customization.
Background
Building Information Modeling (BIM) is used for Building a Building model by taking various relevant Information data of a Building engineering project as a model basis, and simulating real Information of a Building through digital Information. The method has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. Has become a practical new tool in the fields of architecture, engineering and civil engineering.
When BIM is applied to three-dimensional display and space management, the information content of the model directly causes the effect and speed of display and space management to be seriously reduced. To solve these application efficiency problems, the concept of "BIM model lightweight" has emerged. The "BIM model lightweight" is to reduce the volume of the BIM original model through a series of technical means, for example, reduce the number of points, faces, etc. covered by the model, so as to perform lightweight processing on the original BIM model. Although the conventional BIM model lightweight method can realize moderate weight reduction on the BIM original model, the BIM lightweight model is not ideal for 3D quick display, efficient regional space management and the like.
In the building stage of the BIM original model, because a model builder (including an application party) cannot comprehensively predict the application requirements on the BIM model at the later stage, the original BIM model cannot be subjected to targeted space cutting according to the application requirements. The prior BIM model lightweight technical scheme does not support the direct definable space cutting on the lightweight BIM model and stores the cut space model as an independent lightweight model.
In the prior art, if a local space model in an overall model needs to be obtained, the following two approaches can be adopted:
one, separately construct the original BIM model of this local space, such as a separate reporting room, a separate conference room, etc. The weight reduction of the local space BIM model can be performed only by itself. The method has poor flexibility and long modeling period, and the original BIM is modified, so that the overall BIM model and the local BIM model are inconsistent.
Secondly, the local space model is obtained by hiding certain component information of the lightweight integral BIM model and only showing relevant components required by an application scene, such as a certain floor and the like. However, the hiding mode cannot change the weight of the lightweight model, so that the size of the model cannot be reduced or the loading speed of the model cannot be increased.
In addition, if the space management application is to be implemented by using a conventional BIM model, then it is necessary to add the device entities to be managed in the future and their corresponding attributes when building the BIM model. This requires that the type, number, parameters, brand, application scenario, etc. of the later managed devices be known before BIM modeling, which is clearly not realistic. The invention also provides a possibility as follows: for the same space management requirement, the user can add equipment entities and corresponding attributes thereof on the cut space model to meet the requirement.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a BIM model lightweight method based on scene customization, which has the advantages that the model can be cut according to actual application scenes, the model is closer to the requirements of users, and the like.
In order to achieve the purpose that the model can be cut according to the actual application scene and is closer to the requirements of users, the invention provides the following technical scheme: a BIM model lightweight method based on scene customization comprises the following steps:
step 1, uploading an original BIM model file established by a professional through a BIM model conversion API, wherein the original BIM model file is an IFC model file;
step 2, uploading the IFC model file to a BIM lightweight engine by a BIM model conversion API to generate a lightweight model;
step 3, storing the generated lightweight model to a lightweight server to uniformly manage the lightweight model;
step 4, displaying the lightweight model on the lightweight server to a user through the lightweight model display API;
step 5, a user downloads the lightweight model to the local through a webpage client, and the same lightweight model is displayed and edited through a lightweight model display tool according to different scene requirements to obtain a cutting definition model of scene definition;
step 6, the user transmits the cutting definition model to a lightweight model cutting API;
step 7, transmitting the cutting definition model and the original lightweight model to a lightweight model cutting engine together by a lightweight model cutting API;
and 8, cutting the original lightweight model by the lightweight model cutting engine according to the cutting model to obtain a new lightweight model, and storing the new lightweight model file in a lightweight server.
Optionally, the step 2 specifically includes:
the BIM conversion API uploads the IFC model file to a BIM lightweight engine, the IFC file is converted into a DAE file, and the DAE file is converted into a gITF file; then, BIM model metadata information is extracted from the IFC file, the gITF file and the BIM model metadata information are combined, and a lightweight BIM data model is generated
Optionally, the method further includes: the whole lightweight pipeline is deployed to a cloud server, and file uploading, conversion, storage and downloading services are provided in a standard WebAPI mode.
Optionally, the method further includes: all operations of the lightweight model can be completed on the cloud server, and extraction, removal, export and storage services of model components are provided in a WebAPI mode.

Optionally, step 7 further includes: and cutting the graph boundary of the cutting definition model and adding manual marking operation through a lightweight model cutting API.
Advantageous effects
Compared with the prior art, the invention provides a BIM model lightweight method based on scene customization, which has the following beneficial effects:
according to the method, the BIM is defined and cut in the logic space and is stored into the independent lightweight model, so that the processed lightweight BIM model file is smaller, and the loading and displaying speed of the model is higher. Meanwhile, the method can also avoid the condition that the lightweight processing of the BIM model is implemented by professional BIM modeling personnel, and the whole lightweight period and cost are shortened.
According to the invention, after the original professional BIM model is lightened, cutting is carried out according to a specific application scene, so that the cut scene is generated at an application side instead of an original modeling side. The space cutting can be carried out aiming at the actual application scene, and the requirements of users can be better met.
Meanwhile, space cutting according to a specific application scene can be directly performed on a light-weight displayer instead of professional BIM software (such as Revit), so that labor cost is saved, and meanwhile, a manufacturing process is shortened. Because the cut model only comprises BIM components required by the scene, the volume of the file can be reduced to the maximum extent, and the loading and displaying speeds of the model file are greatly improved.
