Copy selected parts and their mates from one assembly to a new assembly

SF 2009-01-20

I have an assembly containing a couple of parts which arerelevant to another assembly.

Does any one know how to select certain parts from one assembly andcopy them and their mates into another or a new assembly??

This functionality would save me from having to insert each partinto the other assembly and then mate them all again.

Thanks,Solidworks Assemblies
