Blades Design and Web Drawing of Axial Flow Pump

To solve the rapid design and accurate drawing of axial flow pump blades,the lift method is coded using Visual Basic and dynamic database technology.Through programming interface of AutoCAD ActiveX Automation,blade drawing accuracy is improved by means of calling for spline functions.For Web browse of blade an approach of PlotToFile combined with ePlot is proposed,it can automatically convert blades drawing to DWF format.
