Embodiment 1

[0060] Use the above method to control the conference scene:

[0061] 1. First, deploy the BIM lightweight pipeline on the cloud platform, including the lightweight API described above, model cutting API, etc.;

[0062] 2. Obtain the 32-story commercial / office building model through the BIM modeling center in the format of IFC file;

[0063] 3. Upload the file to the cloud platform, convert it into a lightweight BIM model through the pipeline, and display the entire model effect through the web BIM display;

[0064] 4. There are many multi-functional conference halls in this building that need to be automated scene design, including brake air conditioning, fresh air control, video equipment control, lighting control and access control, etc.;

[0065] 5. Based on specific scene requirements, select the building components in the No. 1 multi-functional conference hall and the equipment in the room, such as air-conditioning controllers, projector equipment and lighting, by filte...

Embodiment 2

[0069] Use the above method to transform the room usage scene:

[0070] 1. First, obtain the 32-story commercial / office building model through the BIM modeling center in the format of IFC file;

[0071] 2. Upload the file to the cloud platform, convert it into a lightweight BIM model through the pipeline, and display the entire model effect through the web BIM display;

[0072] 3. A certain room in this building is a rental room, which is transformed into a conference room at the request of the customer, but the room is not defined as a conference room in the original BIM model;

[0073] 4. Based on such requirements, filter the lightweight model by using information such as floor, area and room name, select the building components in the room and the equipment in the room, click the button to generate a lightweight model of the conference room, and confirm in the model preview window. Select, and finally click the Export Model button;

[0074] 5. The newly generated model w...

Abstract

The invention relates to the technical field of BIM, and discloses a scene customization-based BIM model lightweight method. The method comprises a series of lightweight operations of uploading an original BIM model file, generating a lightweight BIM data model and the like. According to the technology, after a professional BIM original model is lightened, corresponding space cutting is carried out according to a specific application scene, so that the cut scene occurs on an application side instead of a model design side, and the space cutting can be carried out according to an actual application scene and is closer to user requirements. An original BIM model is defined and cut by a logic space, and is stored as an integral BIM lightweight model or a plurality of independent BIM lightweight models of specific space areas. According to the method, the overall or local BIM model file volume is smaller, and the model loading and displaying speed is higher. According to the method, the situation that the lightweight of the BIM model must be responsible for professional BIM personnel can be avoided, the lightweight period of the BIM model is shortened, and the lightweight cost is reduced.

Description

technical field [0001] The invention relates to the technical field of BIM, in particular to a method for lightweighting a BIM model based on scene customization. Background technique [0002] BIM (Building Information Modeling, Building Information Modeling) is based on the relevant information data of the construction project as the basis of the model, to establish the building model, and simulate the real information of the building through digital information simulation. It has eight characteristics of completeness of information, relevance of information, consistency of information, visualization, coordination, simulation, optimization and plotting. It has become a useful new tool in the fields of architecture, engineering and civil engineering. [0003] When BIM is applied to 3D display and space management, the amount of information in the model will directly lead to a serious decline in the effect and speed of display and space management. In order to solve these a...
