Dynamo-based steel truss column modeling method

Abstract

A Dynamo-based steel truss column modeling method is characterized in that a program is written through visual programming provided by a Dynamo plug-in of Revit, an input port, an output port and a component execution node are written in Dynamo, then different parameters are continuously input, whether a steel truss column can pass operation or not in different steps and different working conditions is tested, and after programming is completed, the program can be operated in a Dynamo player menu of Revit, a Dynamo player only displays dialog boxes of various input parameters and displays a final operation result, and a finished product is imported into the Revit to complete steel truss column modeling. The applet has the advantages of being simple in interface operation, efficient in modeling, quick in operation and the like, and the defects that in Revit three-dimensional design, steel truss column modeling is complex, the modification difficulty is large, and parameterization is complex are overcome.

Description

technical field [0001] The invention belongs to the technical field of BIM building modeling, and in particular relates to an automatic modeling method for steel grid columns based on Dynamo. Background technique [0002] Large-space structures in industrial and civil buildings are widely used in the form of grids, especially in industrial buildings such as waste incineration power plants, almost all of which use rectangular steel grid columns. With the advancement of national BIM technology and the development of three-dimensional forward design of buildings, using Revit’s conventional model and other methods to build grid columns have many rods and complex spaces. The parameterization takes up a lot of computer memory space and is difficult to modify. The architectural design process is always changing, so the model must be updated at any time. [0003] It is known that the establishment of a three-dimensional model can be completed by using the "metric conventional model"...

[0003] It is known that the establishment of a 3D model can be completed by using the "metric conventional model" of Revit, but there are still the above problems, even if the parametric modification is very difficult
