Abstract

The present invention proposes a BIM geometric model construction method for large-volume complex buildings, by layering, dividing and classifying the BIM model; establishing the parameterized component and component library required by the project file; establishing the unified requirements of the overall project file The template files of each sub-project are established by calling the unified component and component library; based on the basic positioning information of the sub-project file, the link parameters of each sub-project are established by using the spatial geometry algorithm, and each The BIM models of the sub-projects are linked and bound to complete the establishment of the BIM model. The layered and block-based lightweight modeling scheme of the present invention reduces the complexity of the model and makes the modeling process easier to implement. At the same time, the modeling process can be carried out on multiple terminals, which greatly improves the modeling speed. In addition, it can be uploaded to the cloud The unified parameterized family library is convenient for calling and parameter definition at any time when the sub-project is established, reducing the repetitive modeling process and greatly improving work efficiency.

Description

technical field

[0001] The invention relates to the technical field of building engineering informatization, and relates to a building information model building method for large-scale and complex buildings. Background technique

[0002] BIM (Building Information Modeling) is a new technology emerging in the construction industry. Its core is a complete and highly integrated three-dimensional information model based on various relevant information data of the entire life cycle of the building. Improve the informatization and integration of construction projects throughout the life cycle of bidding, construction and operation and maintenance management.

[0003] Establishing a three-dimensional information model of a building based on BIM technology is the need for architectural design and in-depth design. At the beginning of the application of BIM technology, it is necessary to construct the model. Only for the architectural structure profession, a complete BIM model is conv...
