I'm in the Automotive sector and have found that deleting history whenever
you can helps a bunch, especially if your machine hasn't got a lot of memory
(ours now have half a gig and still I delete history asap).
This only holds true for static models (i.e. if you don't want to animate
surfaces) as you will need the history then.
Also check your tolreances in construction options; I can't be 100% ( but am
>98%) about this but if they're set to small (i.e. less than .01) then stuff
can take a long time to calculate, or even cause crashes when you haven't
got enough memory. If just before crashing Alias seems to hang for a good
deal of time, then pul up your task manager and see how much memory it's
using. If it is increasing to about 2x your physical memory size then the
above scenario seems to have hit you.
Trims in general can sometimes be the cause of the crashing, and you will
probably find it's one single trim that's causing you problems. If you can,
try rebuilding the CoS of the offending surface with a different tolerance,
this often has shown to help for me.
Oh, and did I mention how important memory is?
