Method for carrying out spatial operation on BIM model based on IFC format

Abstract

The invention discloses a method for carrying out spatial operation on a BIM model based on an IFC format, and the method comprises the steps of providing the spatial information in a configuration file manner based on a concept of a tree-shaped structure in a data structure. Through the program analysis, the space structures of different levels of the BIM model can be operated. According to the invention, regardless of operating the bottom-layer space component from the top-layer space component, or operating the top-layer space component from the bottom-layer space component, the operation is clear, controllable, convenient and fast. Based on the scheme adopted by the invention, the BIM modeling personnel still carry out modeling according to an inherent working mode during modeling, andthe extra space business consideration is not needed. And after the modeling is completed, the system software developers only need to be guided to write one spatial configuration file.

Description

technical field [0001] The invention belongs to the technical field of intelligent buildings, and relates to a method for spatially operating a BIM model based on IFC format. Background technique [0002] At present, the general file format of BIM model in the field of intelligent building is IFC (Industry Foundation Classes), which is a construction engineering data exchange standard formulated by IAI (International Alliance of Interoperability). The IFC standard has the following three characteristics: 1. The IFC standard is oriented to the field of construction engineering, mainly industrial and civil buildings; 2. The IFC standard is open and open; 3. The IFC standard is a data exchange standard for users to exchange and share heterogeneous systems data. [0003] The core technology of the IFC standard is divided into two parts: how to describe engineering information and how to obtain engineering information. At present, the IFC corresponding to the model is classifie...

Problems solved by technology

Therefore, through the organizational structure of traditional IFC, the model can only be operated as a whole according to the type of the model, but the same spatial area cannot be operated as a whole.

For example, you can only operate all the walls, all the roofs, or all the doors and windows at the same time; but you cannot operate a room with four walls, a floor, a ceiling, pillars, furniture, etc. inside the room at the same time.

Therefore, according to the traditional IFC organizational structure, it is impossible to conduct overall operations on the geometric space with the room as the research object, or to operate the room driven by data.
