Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0056] Such as Figure 1 to Figure 6 An information extraction method based on a revit element model is shown, including the following steps:

[0057] S1. Revit three-dimensional modeling: use the building information modeling software REVIT to establish a three-dimensional building model, which includes multiple unit projects such as buildings, structures, and mechanical and electrical installations;

[0058] S2, Revit secondary development platform construction:

[0059] The operation of RevitAPI to realize software function expansion is any one of the following two modes:

[0060] A. Complete through the interface of the external command (IExternal Command): the interface of the external command has one and only one abstract function Excute, which is called as the main function when the plug-in is running, and the plug-in is ...

Abstract

The invention relates to an information extraction method based on a revit primitive model, belongs to the technical field of building information models, and solves the technical problems of difficult information interaction and data loss among professions in a BIM technology development process. According to the solution, BIM mainstream software revit is adopted, secondary development is conducted on the basis of an API of the BIM mainstream software revit, a plug-in for extracting component model information is created, and information reading and one-key exporting are facilitated; seamlessmutual conductance between software can be carried out by utilizing the extracted information, so that extraction and interaction of the revit model information are simpler and more efficient. On thebasis of the prior art, the method is not limited to format conversion between software any more, information interaction and data transmission are conducted through the original primitive model carrying parameters, the problem of information isolation and faulting between software of all parties can be effectively solved, and the data interaction efficiency in the BIM application technology is improved.

Description

technical field [0001] The invention belongs to the technical field of building information models, and in particular relates to an information extraction method based on a revit graphic element model. Background technique [0002] BIM technology is the development trend of today's construction industry. The so-called BIM (Building Information Modeling) technology is the digital expression of the entire physical facilities and functional characteristics of the project using a three-dimensional parametric building information model. Therefore, the core of BIM technology information is in the construction project. stage to achieve information sharing and data interaction, and improve the degree of information interaction. [0003] In the existing technology, due to the inconsistency of the BIM software interface, the problem of data loss greatly restricts its development, information islands still exist, BIM technology has not fully realized data collaboration, and all parties...
