Description
Technical Field
The invention relates to the technical field of building information models, in particular to a data generation method for a Building Information Model (BIM).
Background
The Building Information Model (BIM) is a shared digital representation of the physical characteristics, functional characteristics and management elements of a full-life engineering project or its constituent parts. With the popularization and application of the BIM technology in China, many enterprises establish own BIM data and management platforms and correspondingly establish own BIM standards of the enterprises. The BIM data is basic data and a sharing unit which run through the whole life cycle of the building engineering, and comprises geometric information and service information, wherein the geometric information (GeometricInformation) represents a group of parameters of the spatial position and the self shape (such as length, width, and height) of a building or a member, and usually also comprises the spatial mutual constraint relationship among the members, such as the relationship of connection, parallel, vertical and the like; the service information (professional information) is other information of the building and the member besides the geometric information, such as material information, price information, various professional parameter information and the like.
At present, the data of the BIM has no unified standard temporarily, and the BIM business data established by different enterprises are different, and the consideration on the information exchange of project management with multiple stages, multiple targets and multiple resources is little. This situation restricts the sharing and use of the BIM technology in products at different stages inside an enterprise, and makes the data sharing and use between different enterprises more difficult, which not only restricts the application and popularization of the BIM, but also increases the operation and maintenance costs of the enterprise.
To this end, we propose a data generation method for the building information model BIM to solve the above-mentioned problems.
