| Abstract: | Aimed at the drawbacks of bottom-up product design process in traditional 3D CAD tools,a top-down 3D feature modeling method is presented. The exploitation procedure of top-down assembly design system is put forward. The important parts are assembled and the other parts are designed. It supports the whole process of the product design from conceptual to detail design and an example for reducer is given. |
