Parametric Design Based on Inventor in the Application of Gas Insulated Switchgear

For most enterprises, product design is particularly critical. With the rapid development of information technology, such as Three Dimensional Computer Aided Design(3D CAD) technology, parametric design has become an important method of virtual design. This paper firstly describes the principles of the parametric design. Then, it introduces the three main methods of the parametric design under the Inventor software platform. Focused on how to realize the parametric design of the parts and components by using iPart and iAssembly mechanism and associated external data tables (such as Excel) function. Based on analysis of Gas Insulated Switchgear(GIS)with parametric techniques, it applied such kind of parametric design to a switch plant, as a demonstration of enhanced efficiency of product design and reduces repetitive work.
