Parametric design on belt conveyor roller

To solve parametric drawing problem of belt conveyor roller design,uses inlays language VBA principle and method to achieves the parametric design process of the belt conveyor roller components.uses inlays language VBA to writing drawing program,using this application,designers can input the corresponding parameters to get the result of roller drawing to get belt conveyor roller drawings and assembly drawings and other drawing results.The parametric design method reducts design cycle to some kinds of components,reduce the designer’s drawing labour intensity,and enhances the drawing quality and efficiency.
