【Abstract】 In this paper,the parameterized modeling process and the feature modeling implementing method of the pump guide blade are analyzed in detail.Using ARX,the secondary developing tool of AutoCAD on MDT (Mechanical Desktop) platform,the guide blade CAD software system realized combining the calculation of the hydraulic modeling, engineering drawing with 3D solid modeling.In the end,the feasibility of applying the parameterized feature modeling to the guide blade CAD system is confirmed by taking a run instance,which shows that it is in favor of improving design quality and cutting design time of guide blades.更多还原
