Abstract：According to the extensive application in which 2D drawing is used to devise the model ofcentrifugal pump blade of impeller, the paper puts forward two kinds of method to draw 3D solid molde of pumpimpeller. In addition more attention has been paid to the study of smoothness of curve and surface. As a resultit supplies a good model for further study on CFD and NC.
