I'm doing big componet modeling using solidworks.This component's main assembly having much sub-assy, few assy's having motion like moving within limits. In this sub-assy working fine with motion itself only. while import in main assy i can't able to mate this sub-assy with main assy showing errors like over defined. but in error box what are the error showing all mates are important, i'm trying lot of time i can't able to solve this.So kindly share your suggestion here.

Thanks in advance
