Problems solved by technology

[0003] Traditional BIM model lightweight and application software use a single BIM model file as the smallest management unit to load the model, and realize component-level display and query at the front end. In special scenarios, multiple model files are assembled to To achieve multi-discipline centralized display, etc., when there are many components in the BIM model, there is a problem of low loading and display efficiency
[0004] At the same time, in engineering applications, there is a need for comparative analysis of BIM designs (components) at different stages of local parts, and it is difficult to implement in traditional methods

Embodiment Construction

[0028] Such as figure 1 As shown, a BIM model LOD loading and application method based on component-level management includes the following steps:

[0029] Step 1: Use BIM design software for BIM modeling;

[0030] Step 2: Coding the BIM components with uniform spatial coding rules;

[0031] Step 3: Perform BIM model lightweight processing;

[0032] Step 4: Disassemble and store each component object in the lightweight BIM model file;

[0033] Step 5: The back-end BIM component retrieval service can quickly retrieve BIM component objects corresponding to different model files and different stages through component codes and component spatial correspondences;

[0034] Step 6: Establish BIM application services, package and deliver BIM component objects that meet the requirements according to client requests, and use them for loading, display and business applications of BIM front-end visual application systems;

[0035] Step 7: Through the front-end visualization applicatio...

Abstract

The invention discloses a BIM model LOD loading and application method based on component-level management. The BIM model LOD loading and application method comprises the steps of 1, performing BIM modeling by utilizing BIM design software, 2, encoding BIM components by adopting a unified space encoding rule, 3, performing BIM model lightweight processing and the like. The BIM model loading and application method based on component-level management aims at achieving flexible and multi-layer BIM model and component loading and display, improving the model loading and display efficiency and expanding the application scene of BIM application.

Description

technical field [0001] The invention belongs to the technical field of engineering construction management, and in particular relates to a BIM model LOD loading and application method based on component-level management. Background technique [0002] In recent years, BIM technology has been more and more widely used in the process of project planning, design, construction and operation and maintenance. played an important role. [0003] Traditional BIM model lightweight and application software use a single BIM model file as the smallest management unit to load the model, and realize component-level display and query at the front end. In special scenarios, multiple model files are assembled to To achieve multi-discipline centralized display, etc., when there are many components in the BIM model, there is a problem of low loading and display efficiency. [0004] At the same time, in engineering applications, there is a need for comparative analysis of BIM designs (component...
