Abstract

The invention discloses a method for lightening of a BIM. The method comprises the steps that information data is extracted; in BIM engineering modeling under an existing system, model information data is extracted from an original BIM through use of legal and compliant technical manners; with regard to all the extracted component lists as well as race information data used by each component list, math methods of linear algebra and space analytic geometry will be used to analyze components of the same type in the BIM; and component template data formed by a reusable technologies and global coordinate system matrix data in the BIM are obtained through analysis. According to the invention, the ultra-large data size of the BIM is reduced; bottlenecks of the BIM in storage and transfer are solved; and the BIM is lightened.

Description

technical field [0001] The invention relates to the technical fields of construction engineering industry and computer information technology industry, in particular to a method for reducing the weight of a BIM model. Background technique [0002] BIM has been widely used in the construction industry because of its rich real engineering data and accuracy, and BIM technology has been widely developed domestically and even internationally. The accuracy of architectural engineering is one of the advantages of BIM technology, but because of this, this advantage is exactly its defect and bottleneck in terms of effective delivery and utilization of BIM. As we all know, under the condition of limited bandwidth, the amount of data is directly proportional to the time consumption. Because of this, in order to reflect the actual original appearance of the construction project, the more accurate the BIM model of the construction project, the more data volume, which brings obstacles an...
