Crashing in Alias Studio
Robert Shanks
I'm using Studio 9.5.2. I have a fairly complex model going - industial
design. I seem to be crashing more and more lately as I build this model
up. The design does have quite a bit of trimmed surfaces, rounds for
industial design. There are also a bit of "group"ed parts.
Any ideas?
It seems to crash most when Im trying to move a group of things. When I
crash this way the "saved.M" file crashes while opening.
If I think I'm through with construction history on most parts, would it
be wise to go ahead and delete the construction history? Would that make
it a "lighter" model?
I need to finish this model before the end of the semester Dec 8 and my
progress seems to be slowing.
Cursing and voodoo have helped very little so far...
Thanks - Robert Shanks

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?
Hth,
Kai.

I try and only use construction history now on parts I am dealing with locally.
Now you can move a surface intersection whilst trimmed, and the surfs will
update - no untrimming and retrimming to get the new intersection - this now
causes major problems. Delete history if you can live without it. Also when you
have finished a region or whilst you go along, delete all unneeded COS as they
cause problems too. If you don't ungrouping, grouping, moving etc can cause
youre model to break down. - I know a pain, but you can work around it. If you
can afford it too, zero transforms - makes life easier when everything is in
place.
Again as Kai said, tolerances can be an issue, but if you are modelling for
manufacture they should be at least 0.001mm or tighter so long regen times are
expected. One tip, watch out if you pick up a model someone else has done with
construction history still around. If you load up a model and accidentally /
purposely move a surf in the history 'chain', then the construction settings
you have (they may be different from the other user) will apply, so if they are
different, you may have failing tangency here, curvature not recahed there etc.
Try to find out to what tolerances the model was originally built to and stick
to them and your model will be fine.
When loading up older version wires, 9.0 or before, when it asks you if you
want to update the history / trims, say no, again saying yes can take a long
time as it rebuilds everything with contruction history.
Probably gone on too much now,
good luck,
Mark.

1/1000th of a mm? Can you tell me why? All rp systems I know of are
perfectly capable of dealing with sloppier tolerances than this - they
didn't use to but now they tend to be much more forgiving then they were...
I might be ignorant here (tho I have about a decade of Studio below my belt
now), so let us know in what area and why...
Thanks,
Kai.

I wonder if you can give me any suggestions? I have a new Lenovo, Windows 7 with NVIDIA GeForce GT 555M 1GB graphics card and plenty of memory, and I'm having trouble keeping Alias upright - it crashes after an operation or two, saying:
"Your hardware does not meet minimum specs needed to run the app. Error code 7."
It seems to meet the specs. I can't figure out what Error code 7 is. Any idea what I should be doing?
Thanks, klang
