Volute model creation method based on Revit and Dynamo

Abstract

The invention relates to the field of model creation, and discloses a volute model creation method based on Revit and Dynamo. The volute model creation method is used for improving the modeling efficiency of a volute structure model, and comprises the following steps of: firstly, inputting volute section parameters in a volute single line diagram into a spreadsheet; opening Revit software, and reading the volute section parameters in the spreadsheet by using nodes of Dynamo; determining position coordinates of the circle center of each section according to the parameters, and determining the plane where each section of the volute is located through using an origin, the coordinates of the circle center points of the sections and any point in the z-axis direction by using the nodes; generating a section contour of each section on a plane where each section is located by using the nodes according to the radius of each section; generating a volute solid model according to the section contours by using the nodes; and selecting a volute basic model in the Revit by using the nodes, and shearing the generated volute shape and the Revit structure basic model by using the nodes to form a volute model. The volute model creation method is suitable for volute model creation.

Description

technical field [0001] The invention relates to the field of model creation, in particular to a method for creating a volute model based on Revit and Dynamo. Background technique [0002] With the rapid promotion of Building Information Modeling (BIM) technology in the field of civil engineering, its application in hydropower engineering construction is gradually deepening. To realize the visualization and parameterization of hydropower engineering models, a big problem is the establishment of BIM models with complex and special-shaped structures. [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 hydropower engineering volute structure model is different from civil buildings, and its main features are: (1) The volute section is composed of many circular sections with different radii; (2) The main structure of the volute is mainly generated based on the centerline o...

Problems solved by technology

However, Revit itself has poor functions of creating special-shaped structures and model Boolean operations, and it is difficult to meet the requirements of precise modeling of the volute structure, and the repeated modeling work of different projects will also increase the cost, and bring great harm to the adjustment and modification of the model. These are all restricting the development of BIM technology in hydropower engineering, so how to quickly and accurately establish the volute structure model and realize the parametric modification of the model is very important

[0004] When using revit to create a volute, most of them use the built-in model or volume method, which is cumbersome and cumbersome, and the created model is not accurate due to the poor positioning of the working plane, and it is also very easy to be affected by the software during the creation process. The Boolean operation function is weak, an error occurs, and the creation cannot be completed

The volute section is generally composed of 20-30 sections. Neither the built-in model nor the built-in volume can support so many sections to generate the model together, resulting in the trouble of splitting and creating, and it is difficult to integrate the model with the external concrete foundation. prune
