Newer Versions of Sw and extrude upto function

I have been using Sw since 98, I'm looking at updating as I currently
have 2001+. I'm interested because I have recently seen other woodshops
say they were using Sw for straight cabinet work because of the
flexibility that Sw gives them. This suprised me that Sw was anywhere
near fast enough for them, one shop has 85 draftsman.

We do woodwork and a key issue with me is the ability to create new
configurations faster. I was told on the newer versions that you could
create multiple configurations of an assembly (with parts extruding up
to a surface)and drop the assemblies into another assembly and the
parts would extrude up properly for the different configurations of the
assembly. In our case this would be cabinets dropped into a kitchen.
The advantage would be that I would only have create a new configuation
for the assembly rather than the parts and assemblies. Is this true?

Also has anyone had any experience with this a company called pascam?
