Method for checking whether BIM (Building Information Modeling) file is changed or not

Abstract

The invention discloses a method for checking whether a BIM (Building Information Modeling) file is changed or not. The method at least comprises the following steps that: determining one of at leasttwo BIM files to be checked as a basic file; carrying out data primary processing on the at least two BIM files to be checked; obtaining the geometric vector information and the attribute informationof each modeling construction member in the modeling file; comparing the geometric vector information and the attribute information of each modeling construction member on the same position in each file; and obtaining the change comparison table of at least two BIM files. By use of the method, the modeling construction member in the modeling file which contains mass data is subjected to geometricvector information paired comparison, and therefore, version comparison can be quickly realized. The geometric information and all attribute information of the construction members on the same position in different versions are subjected to paired comparison to judge whether the construction member is changed or not and whether the construction member in the file is deleted or increased or not, and a version change comparison table is efficiently obtained so as to bring convenience for design personnel to check the version change.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method used in engineering for checking whether a BIM model file changes. Background technique [0002] With the development of various projects, design units or construction parties are faced with the problem of dealing with multiple engineering drawings, and in the construction process, drawings are very important, and each historical version in the project needs to be strictly checked. monitor. At present, most of them are confirmed by manual inspection. Even if manual inspection is not used, existing software is used for comparison. However, because the current software is not targeted and due to the large number of BIM model components, different versions The changes and changes of the project files are also very complicated, so there is also a high error rate in the inspection process. Therefore, in order to strictly control the historical versions of large project files,...
