Asynchronous parameterized design for mechanical product based on KBE

A synchronous parametric design by outer-process driven is introduced and a Knowledgebased Parametric Design Platform is developed by object-oriented method in order to solve the problems existing in the mechanical product parametric design.The PDS-MP represents cases by case-based reasoning method synthetically,and on the basis of CAD/API module and using ActiveX Automation technique,the PDS-MP is integrates with CAD.It was intelligently designed by form,rule and feature driven methods,complex 3D models of mechanical product can be established quickly based on the knowledge reused and information shared,it provides a more efficient accurate and practical tool for the digital design and manufacturing.
