Embodiment Construction

[0020] Such as figure 1 As shown, a method of using DYNAMO for revit visual programming tool to realize rapid and accurate modeling and dynamic modification of high-speed railway bridges includes the following steps:

[0021] 1) The railway bridge project to be modeled is decomposed according to the engineering breakdown structure (Engineering Breakdown Structure, EBS), and the different types of object components contained in the railway bridge project to be modeled are obtained. Considering that each type of object component in the railway bridge project to be modeled The basic geometric shape of the model is the same. According to the characteristics of each type of object component, determine the parameters required to realize the characteristics of each type of object component, and then use REVIT to establish a parametric family of each type of object component, obtain a parameterized family database, and build a database containing Parametric primitives and various obje...

Abstract

The invention belongs to the technical field of railway bridge modeling, and particularly relates to a method for using a DYNAMO to achieve rapid modeling and dynamic modifying of a high-speed railway bridge. The method for using the DYNAMO to achieve rapid modeling and dynamic modifying of the high-speed railway bridge is characterized by comprises the first step of decomposing railway bridge engineering to be modeled according to an EBS to obtain different categories of object components, and using an REVIT to build a parameterized model and a parameterized clan database according to characteristics of each category of object components; the second step of building a database of the spatial position of each detailed component corresponding to the object components in the railway bridge engineering to be modeled; the third step of enriching the database obtained in the second step to obtain a modeling database; the fourth step of using a DYNAMO program to call the modeling database and the parameterized clan database to generate a BIM model; the fifth step of modifying the modeling database and the parameterized clan database, and repeating the fourth step to regenerate or modify the BIM model. According to the method for using the DYNAMO to achieve rapid modeling and dynamic modifying of the high-speed railway bridge, modeling is conducted accurately and quickly, and a built model file is small; meanwhile, attributes can be quickly given to the model, thus the information amount of the model is increased, and the model is also conveniently and dynamically modified.

Description

technical field [0001] The invention relates to the technical field of modeling of high-speed railway bridges, and specifically discloses a method for realizing rapid and accurate modeling and dynamic modification of high-speed railway bridges by using a visual programming tool of DYNAMO for revit. Background technique [0002] The use of Building Information Modeling (Building Information Modeling, BIM) technology in the construction of high-speed railways is the direction that is currently being worked on. For high-speed railways, bridges are the mainstay. How to quickly and accurately build bridge BIM models is the basis of BIM applications; REVIT is the basis for BIM applications. Currently the most popular BIM modeling software, it is most widely used in the field of housing construction. In road and bridge engineering, the workload of modeling is usually huge for a bridge of tens of kilometers in one bid section, and the layout of the bridge is based on the curve of sp...
