What version of Alias? Alias 3 is from ~1993 or so, and from version 7, it still looks pretty much the same as the current Autodesk Alias suite, minus all the newer stuff. If you mean PowerAnimator, then the last version was 9.0 before they renamed it to Studio Tools and removed all the animation stuff by Studio Tools 10 (or that is how I understand it)
best to point your browser to "Help\bookshelf.html"
An interesting note - the Alias software has or is missing modules depending on the license you have - for example you can have Studio enabled, or PowerAnimator, or Autostudio. What I always found interesting is that there is a mode that can be a mode enabled called "Maya PowerModeler"
I attached some splash screens of the different modes of Alias 9
ya really dope guy completely legit he deleted nothing his old work was still on there looks like he was learning maya and animated an entire scene. love it when sellers just leave everything. makes it easy and fun.
I've been playing around some more with Alias and various license features - came across a working "Maya PowerModeler" feature (I think), it seems to have some pretty advanced surface modeling features, but no polygon stuff. Pretty interesting stuff
