Based　on　the　analysis　of　product　model　characteristics　of　multidisciplinary　collaborative　design　(MCD),　multiple　views　model　expressed　by　an　extended　object-oriented　method　is　introduced　to　satisfy　the　requirements　of　different　discipline　designers　for　product　information　interaction　and　share.　A　product　modeling　system　for　multidisciplinary　collaborative　design　is　proposed,　and　the　modeling　method　of　discipline　view　model　under　the　network　environment　is　given,　which　can　effectively　support　the　evolution　of　product　model　and　improve　the　flexibility　of　product　modeling.　The　clutch　is　illustrated　to　validate　the　proposed　methods.　©　(2010)　Trans　Tech　Publications.
