A method for comparing the fittingness of a two-dimensional drawing in engineering, at least comprising the following steps: A. obtaining vector and bitmap information of a standard drawing which serves as a foundation and of a project drawing; B. carrying out hash operation on entity types and characteristic points in the vector and bitmap information, and comparing project information of the same hash value; C. calculating at least one or more pieces of information out of an entity change percentage, an area difference percentage, a manual intervention area change percentage and a pixel difference percentage according to the comparison result; and D. obtaining drawing fittingness information according to the obtained information and difference entity weight information. The described method only compares the same parts of a project drawing and a standard drawing, that is, the ratio of an entity in the project drawing that is the same as that in the standard drawing multiplied by a corresponding ...

Disclosed in the present invention is a method for checking whether a BIM model file is changed. The method at least comprises the following steps: determining one of at least two BIM model files to be checked as a basic file; performing initial data processing of the at least two BIM model files to be checked; acquiring geometric vector information and attribute information of model components of the model files; comparing the geometric vector information and attribute information of model components of the files at the same position; and acquiring a change comparison table of the at least two BIM model files. The method of the present invention can quickly achieve version comparison by comparing geometric vector information of model components of model files comprising a massive amount of data. By comparing geometric information and all the attribute information of components of different versions at the same position, the invention determines whether components are changed and whether ...
