It is difficult to conduct parametric design due to the plicacy of tooth profile. My paper mainly studies 3D parametric model system of involute gear by the UG/Open API、 Grip and VC++ based on Unigraphics secondary development tool. First of all， It is available to carry out the writing of the mnx microsoft foxpro ， the design of dialog box and so on through the development tools carried by UG itself on the basis of the study on Unigraphics and UG/Open API. Besides， the development of language and the programing of involute gear are conducted by the application of GRIP which leads in the idea of parameteric model of involute gear. Secondly， Studied Unigraphics secondary development tool which the UG/Open API for adding application framework and program code . Parametric design has changed the traditional design methods and procedures for products and make the most workload of twodimensional engineering drawing acplished by automatic control. The design focusing on the optimization and creativity of structure largely improve the efficency of design， which is good for the achievement of serialization and renewal of products. Nowadays， the designers are in crying need of achieving parameteric model of gear with large 3D software.
