【Abstract】 Parametric technology define the constraint relationship between dimensions and key elements by means of planning or algebraic equation. It realizes dynamic modification in an existed model and enhances the automatic degree in injection mold design significantly. It has become a very important direction in injection mold research since it was combined with traditional CAD and featured with parametric design. This paper, introduces a structure、 principle and realized method based on a parametric featrue modeling system in detail.更多还原
