Description
Technical Field

Background
With the rapid popularization of Building Information Modeling (BIM) technology in the field of civil engineering, the application of the BIM technology in the construction of hydroelectric engineering is gradually deepened. The visualization and parameterization of the hydroelectric engineering model are realized, and the establishment of the BIM model of the complex special-shaped structure is a great problem.
The BIM technology is proposed by Autodesk company in 2002, and the corresponding BIM modeling software is Revit, and the software is mainly oriented to civil buildings. The water and electricity engineering volute structure model is different from civil buildings, and is mainly characterized in that: (1) the cross section of the volute is formed by a plurality of circular cross sections with different radiuses; (2) the volute main body structure is mainly generated by means of a volute center line, and the volute center line is generally a space arc curve with different distances from a center point. The Revit self special-shaped structure creation and model Boolean operation functions are poor, the requirement of accurate modeling of the volute structure is difficult to meet, the repeated modeling work of different projects can increase the cost, great inconvenience is brought to the adjustment and modification of the model, the development of the BIM technology in hydropower engineering is restricted, and therefore how to quickly and accurately establish the volute structure model and realize the parameterized modification of the model is very important.
When a conventional method for creating a volute by using revit is mostly used, a built-in model or a volume is used, the method is heavy and tedious, the created model is not accurate due to the fact that a working plane is not well positioned, and the creation can not be completed due to the fact that software Boolean operation function is weak easily and error report occurs in the creation process. The volute sections are generally 20-30 in number, the internal models and the internal building amount cannot support the generation of models with the sections, the trouble that the models need to be split and built is caused, and the spliced models are difficult to trim with an external concrete foundation.
