The visualization and the parameterization of the hydroelectric engineering model are realized, and one problem facing the visualization and the parameterization is the establishment of a BIM model of a complex special-shaped structure.
BIM technology was proposed by Autodesk in 2002, and its corresponding BIM modeling software is Revit, which is mainly oriented to civil architecture. The hydroelectric engineering volute structure model is different from civil buildings, and is mainly characterized in that: (1) The volute section is formed by a plurality of circular sections with different radiuses; (2) The volute body structure is mainly generated by depending on a volute center line, and the volute center line is generally a space arc curve with different distances from a center point. The Revit special-shaped structure is poor in creation and model Boolean operation functions, the requirement of accurate modeling of the volute structure is difficult to meet, repeated modeling work of different projects also increases cost, great inconvenience is brought to adjustment and modification of the model, the development of BIM technology in hydropower engineering is restricted, and therefore how to quickly and accurately build the volute structure model is important to realize parameterization modification of the model.
When a volute is established by using a revit in the prior art, an internal modeling type or body volume mode is mostly used, the method is heavy and complicated, the established model is inaccurate due to the fact that a working plane is not well positioned, the establishment process is extremely easy to occur due to weak software Boolean operation function, error reporting occurs, and the establishment cannot be completed. The volute sections are generally formed by 20-30, and the built-in model and the built-in volume cannot support the generation of the model together with the sections, so that the model needs to be split and created, and the spliced model is difficult to trim with an external concrete foundation.
