Description

Technical Field

[0001] This invention belongs to the field of BIM component coding technology, specifically relating to a BIM component coding method based on a 3DE platform and a component information database. Background Technology

[0002] To better serve engineering design, construction, and operation and maintenance, BIM models need to carry a large amount of basic information, specifically expressed through massive amounts of BIM components and their attributes. To improve the systematization, standardization, and normalization of BIM component information, BIM components need to be classified and coded, assigning each component an "identity number" and binding it to predefined component information such as stage, role, and profession. This coding increases the value of BIM component attribute information, facilitating the application of information technology for batch automated processing, thereby enabling data flow and mining applications in the construction and operation and maintenance phases.

[0003] The 3DExperience platform (hereinafter referred to as "3DE platform") includes a series of software for design, simulation, and management. The BIM component coding work on the 3DE platform suffers from several problems: a lack of tools for component coding, generally requiring manual attachment, resulting in low coding efficiency; low integration with standards, frequent changes in coding rules, and chaotic version management; a lack of attribute addition functionality, requiring manual addition of numerous extra attributes for model components; and technical issues with low data flow efficiency. Currently, after BIM model coding, existing formats cannot export attribute information, and direct export of geometry and attributes does not correspond. Furthermore, the transmission methods are mostly manual forwarding or Excel export, hindering data flow efficiency.

[0004] The component classification and coding based on 3DE needs to address the "last mile" shortcoming of being compatible with BIM. There are technical problems such as "no tools for BIM component coding on the 3DE platform, low integration of coding with standards, lack of attribute addition function, and low data flow efficiency", which cannot support BIM component coding work. Summary of the Invention

[0005] The purpose of this invention is to provide a BIM component coding method based on the 3DE platform and component information database. This invention solves the technical problems of lack of tools for BIM component coding on the 3DE platform, low integration of coding with standards, missing attribute addition functions, and low data flow efficiency, thereby improving the efficiency and quality of BIM component coding based on the 3DE platform.
