Abstract: A selection and customization system is presented for mechanical design. 3D
parametric model of product is created by SolidWorks. The parametric model is deformed by API
of Solidworks to meet customer's requirement. This system uses the Viewpoint technology to
display the 3D model and allow user to download 2D or 3D mode. The prototype system is
developed and the results are reported. This system can meet the tacks of design.

Key words: product selection, product customization, virtual exhibition, Web3D
