Break link to saved component


I am using Solidworks to create models of store fixtures usingvarious lengths of extruded aluminum.

Previously I used Mechanical Desktop 2.0. Various profiles ofextrusions were saved in a library directory. From there, I couldinsert them as parts into my assemblies and then localize them.Once localized, I could change their length without affecting thesaved library part. All changes to the various parts were savedwith the assembly.

Is there a way to do this in Solidworks? I would think this wouldbe obvious, but it has me scratching my head.

Any insight would be appreciated.
