Problems solved by technology

[0003] There is no suitable platform for tunnel BIM design, and there is no tool for tunnel BIM design, and the efficiency of BIM design is low; the parameterization function of the more popular BIM design platforms currently on the market is weak, and it is difficult to change the model by modifying the parameters after the BIM model is generated. Compared with the traditional two-dimensional design, there are not many advantages, and the efficiency is much lower than the traditional two-dimensional design

Abstract

The invention belongs to the technical field of BIM (Building Information Modeling), and discloses a railway engineering component parameterization method based on Ilogic, which comprises the following steps of: (1) decomposing a railway engineering component into a plurality of basic components according to a railway BIM union standard, and dividing the attributes of the basic components into geometric attributes and non-geometric attributes by combining an IFC attribute; (2) establishing an IFC template of the basic component according to railway IFC classification, utilizing an ilogic technology component to contain a form of an IFC attribute, and pre-writing an attribute value; (3) establishing a parameterized BIM model, setting attribute information and non-geometric information, andparameterizing railway engineering components; (4) the form information is associated with model parameters, different BIM models are obtained by setting different geometric parameter values and non-geometric attributes, and a form driving model is achieved; (5) exporting the model with the IFC attribute information as an IFC file; according to the method, on the basis of parameterization of an ilogistic form, parameters of parts are organically integrated on one form, parameterization of components is achieved to the maximum extent, and the readability of the components and the efficiency ofcomponent design are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of BIM, and more specifically relates to an Ilogic-based parameterization method for railway engineering components. Background technique [0002] In recent years, more and more applications of BIM (Building Information Modeling, Building Information Modeling) have been applied in tunnel engineering, and new projects all have BIM application requirements. However, most of the BIM projects currently being done in China are mostly model-based applications, and very few of them have achieved BIM forward design. The reason is that the current tunnel BIM design has the following problems: [0003] There is no suitable platform for tunnel BIM design, and there is no tool for tunnel BIM design, and the efficiency of BIM design is low; the parameterization function of the more popular BIM design platforms currently on the market is weak, and it is difficult to change the model by modifying the parameters after the ...
