ProEngineer for Unix

[Tristan Lall]

There are both UNIX and Linux versions, and for several architectures.

Wildfire 5.0 was just released (but if past versions are any indication, a lot of moderately annoying bugs will be caught in the next few datecodes). Both WF 4.0 and WF 3.0 are stable, supported and available. So you could definitely go with the UNIX or Linux versions of one of those, if you don't care about having the latest version. (The Linux version has been discontinued for Pro/E Wildfire 4.0 and above. Also, as of Wildfire 5.0 the more esoteric UNIX ones are gone as well: Solaris on SPARC and HP-UX on PA-RISC. So for WF 5.0, the only supported UNIX configuration is Solaris 10 on x86-64.)

The Student Edition is only compiled for Windows, as far as I know, but I suspect that any of the versions which can accept licence files ought to be able to run as Schools Edition (or University Edition, or Commercial Edition). So, assuming it's Schools Edition you're looking for, I'd say it's worth contacting Mark Fischer (mfischer@ptc.com) and asking if he can make those versions available to your team.
