This　paper　presents　a　novel　system　of　feature　based　products　whole　life　cycle　design.　The　proposed　system　is　composed　of　products　layer,　sub-assembly　layer,　part　layer,　characteristics　layer,　property　layer　and　geometry　layer　to　integrate　all　related　information　of　products　whole　life　cycle.　The　system　can　build　the　products＇　design　model　rapidly　and　in　which　the　involved　issues　of　product　whole　life　cycle　can　be　analyzed　and　evaluated.　According　to　the　result　of　evaluation,　the　suggestions　of　redesign　can　be　presented,　and　the　design　parameter　can　be　modified,　then　the　model　can　be　regenerated　and　exported　to　CAD　system.　Finally,　the　practicability　of　the　proposed　method　is　verified　through　an　example.
