Background
The BIM technology is rapidly developed in the fields of building and traffic engineering, a computer informatization technology represented by the BIM technology becomes a research and development direction in the building engineering, and a 2016-2020 outline of informatization development of building industry indicates that the latest information technology taking the BIM as a core becomes a core technology for supporting the technology upgrade of the industry, the change of a production mode and the innovation of a management mode. The integrated application of BIM, an enterprise management system and other information technologies is required to be mastered and realized by design units and construction enterprises.
In order to realize management based on component level in BIM technology application, professional structural components need to be expanded in a directory tree form, so that a user can conveniently position the components, and meanwhile, a one-to-one mapping relation is formed between the components and component categories, but the application in the aspect is rarely realized in the prior art and the prior use.

a method for rapidly generating a structure directory tree in a management platform based on BIM technology is characterized in that:
the method is realized by the following steps:
the method comprises the steps of adding LID coding attributes to components, separating BIM models from the coding attributes, performing tiling and lightweight processing on the models, and associating nodes with the components by using GUIDs (globally unique identifiers), so that the one-to-one correspondence relationship between each node and each component is created.
The method specifically comprises the following steps:
1) when a BIM model is generated, adding an LID coding attribute with a hierarchy concept to each member;
2) when entering a management platform, separating a three-dimensional model of the model from the coding attributes, and putting the GUID and the coding attributes of the component into a database;
3) carrying out tiling lightweight processing on the separated three-dimensional model entity in a management platform;
4) analyzing a database storing the coding attributes in a management platform, and generating tree nodes by using hierarchical coding;
5) the building blocks are bound to tree nodes using GUIDs.
In the step 1), the attribute value of the LID coding attribute is represented in a text mode.
In the step 3), the light weight processing means that only the outline structure is reserved and no parameterization information is contained.

1. the method is simple and convenient, and mainly works by compiling the LID code with a layered structure and adding an attribute when generating the BIM model;
2. the structure directory management is easier to perform in the BIM management platform, the nodes and the components have one-to-one correspondence, the searching and the positioning and the attribute hanging of the component type are convenient, and the professional habit is better met;
3. the model and the attribute information are separated, the platform response speed is higher after the lightweight processing of the model, the attribute database is easier to expand and manage, and the efficiency is higher.
According to the invention, LID coding attributes are added to the components, the BIM model and the coding attributes are separated, the model is tiled and lightweight, and the GUID is utilized to associate the nodes with the components, so that the one-to-one correspondence between each node and the component is established.
