Rapid modeling method for parameterized reticulated shell structure model based on Revit and Dynamo

Abstract

The invention discloses a rapid modeling method for a parameterized reticulated shell structure model based on Revit and Dynamo. The method comprises the following steps: 1) determining shell surfaceparameters and reticulated shell division parameters of a reticulated shell structure to be created according to design requirements; 2) creating a shell surface according to shell surface parametersof the reticulated shell structure; 3) meshing the shell surface; (4) if the reticulated shell is a double-layer reticulated shell, enabling the shell surface to deviate in the curvature direction according to the set reticulated shell thickness to obtain a lower chord shell surface, and carrying out curved surface division on the lower chord shell surface; 5) establishing each truss to obtain a final reticulated shell wireframe; 6) obtaining a reticulated shell structure modeling node packet with an input end and an output end; 7) inputting proper parameters to obtain a wire frame model of the reticulated shell; (8) building all frame families needed by the reticulated shell model, and (9) outputting an upper chord, a lower chord and a web member wireframe to the frame families through Dynamo nodes to complete building of the final reticulated shell structure model. By means of the method, the working efficiency of reticulated shell structure model design can be effectively improved.

Description

technical field [0001] The invention relates to a parametric BIM model modeling technology, in particular to a rapid modeling method for a parametric reticulated shell structure model based on Revit and Dynamo. Background technique [0002] Parametric technology is more and more widely used in the field of construction, especially in reticulated shell structures. Construction engineers and structural engineers need to constantly adjust plans and structural models. With the help of parametric tools, the modeling and adjustment of grid structures can be quickly completed. [0003] Building Information Modeling (Building Information Modeling, referred to as BIM) refers to a visual digital building model constructed with advanced 3D digital design solutions. Parametric models have always been one of the indispensable basic models in the field of BIM applications. [0004] At this stage, it is inconvenient to modify the BIM model of reticulated shell structure. Every modificatio...
