Embodiment 1

[0035] as attached figure 1 As shown, the embodiment of the present invention provides a weak association method based on BIM model, comprising the following steps:

[0036] Step S1, constructing a structural calculation model corresponding to each component according to the BIM model;

[0037] BIM model renderings see figure 1 , all components in the BIM model and their proportions and connections are reflected in the structural calculation model one by one, and the specific shapes of the components in the model are simplified, such as beams in the model, which can be simplified in the structural calculation model as A line segment with the same length; the BIM model can be manually created on the BIM platform, or automatically imported from other software platform data through the secondary development plug-in of the BIM platform. Component categories in the BIM model include beams, columns, and floors.

[0038] Step S2, generating a calculation book unit for each compone...

Abstract

The invention discloses a weak correlation method and system based on a BIM model. The method comprises the following steps: constructing a structural calculation model corresponding to each componentthereof according to the BIM model; generating a calculation book unit for each component in the structural calculation model according to the input information; generating a projection direction construction drawing of the local BIM model according to the input instruction; establishing the matching relationship between the calculation book unit and the components in the local BIM model by weakassociation algorithm; extracting calculation information from the calculation book unit to form labeling information; forming construction drawings based on input instructions according to the drawing specification by the tagging information and the components in the local BIM model. The scheme solves the problem that the construction drawings generated by the strong association method in the prior art are not convenient to modify and adjust subsequently, realizes the synchronization of the labeling information of the construction drawings and the component information of the BIM model, and reduces the limitation of the strong association and the complexity of the secondary software at the same time.

Description

technical field [0001] The invention belongs to the technical field of computer software applications, and in particular relates to a BIM model-based weak association method and system. Background technique [0002] A software system that generates construction drawings for construction, mechanical and electrical industries based on the BIM model. After the construction drawings are generated, the information marked on the construction drawings needs to be reflected on the BIM model components and the two should be consistent. For the construction drawing information and the BIM model Synchronization of component information, there are two existing methods: using a strong association synchronization method; [0003] Customize the parametric labeling unit for a specific category of BIM model components, bind the properties of the labeling unit to the properties of the BIM model component, and bind the label itself to a specific BIM model component, so as to realize the coordi...
