Problems solved by technology

However, Revit itself is difficult to meet the requirements of precise modeling of tunnel structures, and a large number of mechanized repetitive modeling work will also increase costs, and bring great inconvenience to model adjustment and modification, all of which restrict the application of BIM technology in tunnel engineering Therefore, how to quickly and accurately establish the tunnel structure model and realize the parametric modification of the model is very important

Embodiment

[0026] Example: such as Figure 1-5 As shown, this embodiment specifically relates to a Dynamo-based tunnel structure model modeling method, specifically based on the Dynamo for Revit visual programming tool, including the following steps:

[0027] S1: Center point coordinate data processing

[0028] Although there are various forms of tunnel section, they are basically generated based on the centerline of the tunnel, so the coordinates of the center point of the tunnel are very important; The measurement reference point offsets the coordinates of each point to obtain the coordinates of the center point of the tunnel corresponding to the point, thereby obtaining the coordinates of each center point on the center line of the tunnel to be built, and according to the X-axis, Y-axis, and Z-axis The center point coordinates are entered into the three tables of Excel respectively;

[0029] In this embodiment, the length of the tunnel to be built is 0.6 km, which is divided into tw...

Abstract

The invention discloses a tunnel structure model modeling method based on Dynamo. The method comprises the following steps of obtaining coordinates of center points on a center line of a to-be-built tunnel; opening Revit software, programming by using Dynamo, and reading coordinates of each center point to establish a tunnel center line; dividing the center line of the tunnel into a plurality of sections at equal intervals; according to the segment length and the cross section form of the to-be-built tunnel, building a segment family of the to-be-built tunnel; programming by using Dynamo, andaccording to the tunnel center line and the separation control points on the segments, calling a segment family to instantiate to given separation control point coordinates to generate a tunnel main body structure model; and constructing a bypass channel segment family of the tunnel to be built and instantiating the bypass channel segment family to a control point of a bypass channel to complete the whole tunnel structure model. The method has the advantages that the tunnel structure model is quickly and accurately established on the Revit platform on the basis of the Dynamo visual programmingtool in combination with the structural characteristics of tunnel engineering, the modeling steps of the tunnel structure model are simplified, and the modeling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel structure models, and in particular relates to a tunnel structure model modeling method based on Dynamo. Background technique [0002] With the rapid promotion of Building Information Modeling (BIM) technology in the field of civil engineering, its application in tunnel construction is gradually deepening. Through BIM technology, the basic information of the tunnel, including the cross-section, structure, and length of the tunnel, can be included in the entire BIM model to realize the visualization and parameterization of the tunnel model. In the application of tunnel BIM, it is a big problem. It is the establishment of BIM model. [0003] BIM technology was proposed by Autodesk in 2002, and its corresponding BIM modeling software is Revit, which is mainly oriented to civil buildings. The main structure of the tunnel is different from civil buildings, and its main characteristics are: (1) The tun...
