Problems solved by technology

[0002] Railway engineering projects are linearly distributed, with the characteristics of cross-regional, huge engineering volume, and complex construction. The traditional two-dimensional method cannot accurately describe the objective world and provide users with an intuitive display. Therefore, three-dimensional technology has attracted widespread attention.
The traditional 3D modeling method mainly uses manual construction of fine 3D models. Although the display effect is good, the modeling cycle is long, the cost is high, it does not have spatial attributes, and the sharing is poor. The huge data cannot be run smoothly on general equipment. Engineering for high-volume rapid prototyping

Embodiment 1

[0021] A parametric-based automatic modeling method for railway engineering, including the following steps:

[0022] (1) Extraction of required eigenvalues ​​and creation of BIM parametric model

[0023] Automated modeling of railway engineering uses CAD data as the data basis, and BIM model is produced in Autodesk Revit. One of the core features of BIM modeling is model parametric design. , form the smallest component of modeling, use parametric method to describe the geometric, positioning, and material characteristics of the component, and obtain component instances with different shapes by inputting parameter values. That is to decompose the entire model of railway engineering into some standard components, such as piles, caps, piers, and beams. Then extract the parameters of some of the characteristics. For the characteristic parameters of the superstructure data, there are bridge name, pier number, positioning pier number, starting pier number, ending pier number, start...

Abstract

The invention discloses a railway engineering automation modeling method based on parameterization, and belongs to the technical field of building engineering modeling. The method specifically comprises the steps of obtaining environment information data and dimension model data; summarizing the data in EXCEL and introducing the data into cloud platform, depending on platform data, compiling a revit identifiable file by utilizing a C language program, and then automatically reading and generating a BIM model by utilizing the revit; using visworks software for collision inspection to correct the model. The defects that a traditional modeling period is long, cost is high, space attributes are not achieved, sharing is poor, huge data cannot smoothly run on common equipment, and the method isnot suitable for large-batch rapid modeling engineering are overcome. The purpose of one-key rapid batch modeling is achieved.

Description

technical field [0001] The invention mainly relates to a parameterization-based railway automatic modeling method, which belongs to the technical field of modeling of construction engineering. Background technique [0002] Railway engineering projects are linearly distributed, with the characteristics of cross-regional, huge engineering volume, and complex construction. The traditional two-dimensional method cannot accurately describe the objective world and provide users with an intuitive display. Therefore, three-dimensional technology has attracted widespread attention. The traditional 3D modeling method mainly uses manual construction of fine 3D models. Although the display effect is good, the modeling cycle is long, the cost is high, it does not have spatial attributes, and the sharing is poor. The huge data cannot be run smoothly on general equipment. It is suitable for large-volume rapid modeling projects. Therefore, a fast, batch, accurate and geographic modeling me...
