摘要
本文对弯肘型尾水管的三维建模过程进行分析,针对可研阶段由于参数缺少而不足以进行精确建模的情况,提出一种基于控制线选取的方法来进行尾水管不完全建模,并基于Microstation平台程序化实现了该建模过程。结果显示,可以获得造型比较流畅的尾水管三维模型,且该方法同样可适用于其他变截面三维实体的不完全构造。
Based on the analysis of exact 3 D modeling of elbow draft tube, it is difficult that the 3 D modeling to draft tube under feasibility study, where the provided parameters are too poor to model. In this paper, we develop a method based on proper control lines to produce rational draft tube model. The programmatic modeling process is realized on the threedimensional design platform Microstation. The result shows its effectiveness. The same considerations can be applied to more other variable cross-section body without enough modeling information.
