CAD training licenses?

Hello,

This just hit me: are there training licenses available to engineers and designers who want to use/play around with/learn/explore a new cad software for non-commercial purposes and to simply better your cad skills?

A quick google search didn't really turn anything up. There are a lot of student options but I can't seem to find much for engineers/designers.

It looks like solidworks used to have an engineering stimulus program:

I'm not talking just about solidoworks though: what about creo? Nx? All the others?
