By analyzing the modeling m echanism of neutral com m and adopted in collabor ative design system w it h heterogeneous CAD systems, a feature- based m inimum m app ing set is presented. Based on above approach, a prototyp e is developed to f inish the operation transform ation betw een SolidWo rks 2005 and U G N X3. 0 w ith a plug - in style. An example of co llaborativ e design process of a simple pro duct desig n is ap plied to verify t he f easibility of the pro to type. Key words: sy nchr onous collabor at ive design feature - b ase
