The construction industry development plan has clearly defined the direction of accelerating the coordinated development of intelligent construction and new building industrialization. BIM is one of the most important supporting technologies. Limited by factors such as the integration barriers of construction industry elements, process integration barriers, and organizational integration barriers, BIM technology currently still has many shortcomings that need to be improved.

[0003] In the BIM design process of the construction industry, each profession has its own production software, and the model file formats between software are not the same. Format conversion between files will cause model information loss or even errors. At the same time, there is a lack of real-time, linkage and system management between professions, resulting in a large amount of invalid and repeated design work and inefficient collaborative communication.

[0004] Therefore, it is an urgent need to improve the technical content in the BIM design process to seamlessly connect various professional design platforms through a common model file format platform, and provide real-time three-dimensional visualization of the design progress of each professional, reduce the communication cost between professions, and improve the efficiency of collaborative design.

[0005] Referring to the film and television industry, which has a high degree of digitalization and industrialization and a mature system, USD (full name Universal Scene Description) is one of the technologies that can be used as a reference. Compared with other traditional architectural software, it has the advantages of smaller and faster data, and also has an open source data package.
