Problems solved by technology

However, the format model is too large, resulting in slow loading. At the same time, the attribute information is easy to be lost during the file conversion process, and the compliance audit cannot be guaranteed.

Embodiment Construction

[0036] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as figure 1 As shown, a construction drawing design BIM model compliance review method, the method includes:

[0038] Step 1) establish the railway standard component library based on the IFD (International Framework for Dictionaries, International Dictionary Framework) classification code approved by the Railway BIM Alliance, the component library includes geometric attributes and non-geometric attributes related to model compliance;

[0039] The railway standard component library is based on the IFD table 53-railway engineering components, and associates standard geometric and non-geometric attribute information for different components. Taking some components of a bridge as an example, the relationship between component library IFD and geometric attributes and non-geometric attributes is shown in Table 1:

[0040] Table 1

Abstract

The invention discloses a construction drawing design BIM model compliance checking method. The method comprises the following steps: 1) establishing a railway standard component library based on IFDclassification coding; 2) converting a construction drawing design BIM model into a combined file containing hsf and db; 3) judging whether the combined file of the hsf and the db in the step 2) is amodel file through file checking, and judging that the model is unqualified if the combined file is not a model file; if the combined file is a model file, traversing attributes of the design BIM model by the model through attribute checking, comparing the attributes with attributes of the railway standard component library, and ultimately judging whether the model is qualified or not. The methodof the invention can effectively check the construction drawing design BIM model.

Description

technical field [0001] The invention relates to the field of auditing railway engineering construction drawings, in particular to a method and system for auditing the compliance of BIM models for construction drawing design. Background technique [0002] BIM is a multi-dimensional model information integration technology developed based on CAD technology, and it is a digital carrying and visual expression of the physical and functional characteristics of architectural engineering. The application of BIM will provide technical support for the integration of engineering project industry chain, industrialized construction, refined and standardized management. Through the refined BIM information model, information sharing and non-destructive transmission can be realized in the whole life cycle of survey, design, construction and operation, thereby improving the quality and efficiency of engineering construction and bringing great application value to the engineering field.
