Abstract

The invention discloses a 3D (Three-Dimensional) lightweight conversion method based on a BIM (Building Information Modeling) file. The method comprises the following steps that: S1: independently carrying out attribute data analysis and geometric material analysis on an IFC (Industry Foundation Classes) model file, wherein an attribute data analysis process and a geometric material analysis process are not related and can respectively independently operate in parallel; S2: configuring a query server, wherein the query server sets a model component Web end loading priority and inquires and loads building component attribute information and geometric material attribute information in different steps by multiple threads according to the model component Web end loading priority; and S3: through a database query interface of a Restful style, realizing Web front-end 3D lightweight display. The method has the advantages that server hardware configuration requirements are lowered, IO (Input / Output) operation frequency is lowered, the waiting time of front-end users is shortened, and user experience is improved.

Description

technical field

[0001] The invention relates to the field of construction industry information technology, in particular to a 3D lightweight conversion method based on BIM model files. Background technique

[0002] With the introduction of building information modeling technology (Building Information Modeling, referred to as BIM) in the construction industry, the application of BIM technology has been in full swing. One of the application bases of BIM technology is the BIM model. A building involves specialties such as architecture, structure, and electromechanical, so the information carried by a BIM model of a building includes geometric information and attribute information that constitute the building. Therefore, due to the large amount of information carried by the BIM model, the BIM model file capacity is very large, ranging from a few hundred M to a few G, which leads to the need for users to install very large software and Purchase high-performance computer equipm...
