Abstract：The paper introduces the advantage of 3D CAD system-Solidworks and the OLE technology and objects it supports. Analyses the virtues of the double channel impeller when it is in use and the effects the 3D entity modeling haves on the design, production and the theoretic research. Additionally, based on the example of 3D entity modeling of the double channel impeller, it explains the method that Solidworks is developed in VB.
