Embodiment Construction

[0020] A method of using Dynamo to quickly and accurately create a grid BIM model, which is realized by the following steps:

[0021] 1) According to the grid construction material list and the grid construction plan section, use Excel to compile the component information table; the content of the component information table includes: the coordinate information of the grid ball, the specification information of the grid ball, the information of the grid ball Number information, specification information of the member, number information of the member;

[0022] 2) According to the component information table, use Revit to create a variable grid ball family and a variable member family;

[0023] 3) Through the visual programming of Dynamo, the coordinate information of the grid ball in the component information table, the specification information of the grid ball, and the serial number information of the grid ball are obtained in the form of a list;

[0024] 4) Through the sec...

Abstract

The invention relates to a method for creating a network frame BIM model, in particular to a method for quickly and accurately creating a network frame BIM model by using Dynamo. The invention solvesthe problems of long modeling period and low modeling accuracy of the existing network frame BIM model creation method. The method for quickly and accurately creating a BIM model of a grid structure by using Dynamo is realized by adopting the following steps: 1) compiling a component information table; 2) creating a parameterizable space truss ball family and a parameterizable rod family; 3) obtaining coordinate information, specification information and number information of the space truss ball; 4) grouping the spherical center points of all the space truss balls; 5) generating a spherical center point of each space truss ball; 6) creating an example of the space truss ball; 7) obtaining a BIM model of the space truss ball; 8) obtaining coordinate information of the space truss balls attwo end of each pole; 9) obtaining specification information of the pole and number information of the pole; 10) grouping all the poles; 11) creating an example of the pole; and 12) obtaining a BIM model of the pole. The method is applicable to the construction of the space truss.

Description

technical field [0001] The invention relates to a method for creating a grid BIM model, in particular to a method for quickly and accurately creating a grid BIM model by using Dynamo. Background technique [0002] Because of its small space force, light weight, high rigidity, and good seismic performance, the grid frame is widely used as the roof of exhibition halls, gymnasiums, railway stations, museums and other buildings. In recent years, with the continuous development of information technology and the vigorous promotion of BIM technology, creating a grid BIM model has become an important link in grid construction. However, practice shows that due to the limitation of its own principles, the existing grid BIM model creation methods generally have the problems of long modeling cycle and low modeling accuracy, which seriously affect the efficiency and quality of grid construction. Based on this, it is necessary to invent a new method for creating a grid BIM model to solve...
