Trapezoidal flat grid roof modeling method based on Dynamo

Abstract

The invention provides a Dynamo-based trapezoidal flat grid roof modeling method, which comprises the following steps of: writing nodes by utilizing visual programming provided by a Dynamo plug-in of Revit, writing related nodes of input and output ports and components in the Dynamo, then testing whether the trapezoidal flat grid roof can pass and run in different steps and under different working conditions according to different input parameters, and if yes, determining whether the trapezoidal flat grid roof can pass and run under different working conditions. After programming is completed, operation can be carried out in a Dynamo player menu of Revit, a Dynamo player only displays dialog boxes of various input parameters and displays a final operation result, a finished product after operation is completed is imported into Revit to complete establishment of the trapezoidal flat grid roof model, and the method has the advantages of being simple in interface operation, efficient in modeling, rapid in operation and the like. The defects that in an existing Revit three-dimensional design, flat grid modeling is complex, the modification difficulty is large, and a trapezoidal flat grid roof Revit cannot be modeled are overcome.

Description

technical field [0001] The invention relates to a method for modeling a roof of a trapezoidal flat grid frame based on Dynamo. Background technique [0002] Large space structures in industrial and civil buildings are widely used in the form of grids. 3D architectural design needs to accurately and vividly express the spatial grid model. With the advancement of national BIM technology and the development of 3D forward design of buildings, the conventional model of Revit is currently used. Other methods to build a network frame, there are many rods, complex space, huge workload, parameterization takes up a lot of computer memory space, and it is easy to cause crashes; while the architectural design process plan is always modified and changed, if you use Rhino and other software to model and import, Modification is a lot of work and requires the model to be updated at any time. [0003] It is known that the use of Revit's "metric conventional model based on curtain wall fill ...
