BIM model-based component screening and checking method and system

Abstract

The invention discloses a component screening and checking method and system based on a BIM model, and relates to the field of BIM model checking. The method comprises the following steps: acquiring all components at each defect position in a preset BIM model, inputting component parameters of the components into components meeting screening conditions in a screening plug-in, and marking the components as first feature marks; importing a preset BIM model of the component with the first feature mark into the virtual reality model, and highlighting the first feature mark in the virtual reality model; and modifying the selected component with the first feature mark in the Revit. According to the method, the initial unreasonable positions in the BIM model of the building are automatically obtained, the demand components of the customer are highlighted in the virtual reality model according to the first feature marks, the customer can conveniently view and modify the demand components, and after visual inspection of the virtual reality model, the situation that problems in the design stage are transmitted to the construction stage is reduced as much as possible.

Description

technical field [0001] The invention relates to the field of BIM model checking, in particular to a component screening and checking method and system based on a BIM model. Background technique [0002] The current BIM (Building Information Modeling, Building Information Modeling is a new tool for architecture, engineering and civil engineering, used to describe computer-aided design that is mainly based on three-dimensional graphics, object-oriented, and related to architecture.) The platform generally uses Revit The structural model is used to set the architectural drawings, and in a structural floor plan of a Revit structural model, corresponding to the linked CAD structural base map, in the structural floor plan, it is often possible to simply check whether the component contour edge of the built component information is consistent with the CAD base One-to-one coincidence of the contour and edge of the component width can meet the requirements of checking whether the com...

Problems solved by technology

But for some Revit structural models of large basements or large public buildings, there are many types of component sections and a large number of components in a structural floor plan, and the operation of obtaining component information by touching the component with the mouse every time is repetitive and heavy. , checking by memory will easily miss and cause repetitive checks, and also easily lead to missed checks
