Abstract

The invention discloses a BIM (Building Information Modeling)-based model pre-matching method and system. The method comprises the following steps: marking a connection position of each to-be-mounted component to be mounted on a construction site according to a reference model of the construction site; performing defect identification on each connection position on the reference model in sequence to obtain a defect sequence; repairing the reference model according to the defect sequence to obtain a corrected model; sequentially matching each connection position on the correction model with the component model set to obtain a pre-installation model; the pre-installation model is converted into the construction drawing, intelligent aided design of a BIM three-dimensional model can be achieved, modeling of all components in combination with the actual construction site environment can be achieved, particularly for some construction objects with multiple components and the complex installation environment, modeling can be accurately conducted on the construction environment and various devices and pipelines to be installed, and the construction efficiency is improved. Errors of a complex space curved surface in an engineering model of a construction site are reduced, and the refinement degree of the BIM model is improved.

Description

technical field [0001] The disclosure belongs to the field of BIM modeling technology and computer-aided design technology, and in particular relates to a BIM-based model pre-matching method and system. Background technique [0002] At present, modeling through BIM has been gradually popularized and applied in construction. Generally, CAD software, Rhino3D, RhinoInside and Revit are used to build three-dimensional BIM models. Modules or preset component templates are used for modeling. It is difficult for existing technical means to model each component in combination with the actual construction site environment, especially for some construction objects with many components and complex installation environments. Modeling of the construction environment and various equipment and pipelines to be installed, and the accuracy of the model is very low due to various reserved holes, pipes and other macroscopically imperceptible small parts in the complex construction environment, ...
