Speed and large assembly drawings

[Anonymous]

We are running Inventor 11 on 2.53 GHz 1 Gig Ram
We have an Assembly approx. 1500-2000 parts. this assembly is made up of sub assemblies and there are no stray parts in the master assembly. It is an assembly of tanks, work platforms and piping. Our user has created a drawing with 5 sheets. each containing approx. 4-5 views.
all the views (almost) are shaded. He set up the master assembly with alot of design views and each view in the drawing is of the whole master assembly but you only see what he wishes you to see by his design views. I hope this is not to hard to follow. Is it possible that the way in which this drawing is set-up is a part of our issue.
We also tested this on a brand new 4 gig ram machine and we had the same results. The program goes into the red and we get the memoery 80% error, shortly after is crashes out.
We ran this test on 2 machine one local and off the network and one on the network. althought there was a minor difference there was not much.
Is there anything obvious that we are missing. Are we doing something that should not be done in Iventory, with this drawing.

Well, it's a though drawing for sure!What you can do is use the 3GB switch.
Goto 'Control panel' and select system (double click). Go to the tab
'Advanced' and click 'settings' in the 'Startup and recovery' section. A new
screen appears now click on the edit button. The file you're looking at is
the 'boot' file.

There should be a line like this (not the same per se):

multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP
Professional" /noexecute=optin /fastdetect

Add copy the line and paste it underneath the other. Now add ' /3Gb' to the
end of the line and rename the middle section:
Microsoft Windows XP Professional TO Microsoft Windows XP Professional
3GB (or something similar)

multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP
Professional 3GB" /noexecute=optin /fastdetect /3GB

If you reboot your PC you'll have an extra 1 Gb address space. Maybe just
enough to work on your files? Good luck!

Will this be of any benifit if we only have 1 Gb of Ram?

Absolutely! This is address space we're talking about, not RAM. If you don't
have enough RAM, Windows will work with Virtual Memory. It takes a little
bit of space on your hard drive and simulates RAM. Nice feature, but a lot
slower than normal RAM. Usually windows takes 2Gb and the remaining 2 Gb is
for your other programs. Using the 3GB switch will limit windows to 1 Gb and
you'll get 3 Gb of address space! 4 Gb is the maximum number of
possibilities (32 bits system = 2^32 = 4 Gb) so there's no way you'll get
more right now. That's the reason why 64bit systems are coming on the
market; more address space (not just twice as much, but a whopping 2097152
TB! Well, they've decided to limit that amount to one TB (1000 GB)... Fair
enough!)

Hi kitrgy

I think than in your case it doesn`t solve your problem. 3 Gb switch improves performance on machines with more than 2 Gb RAM. You should attempt turn on 3 Gb switch on the other machine with more RAM.
You can also try to turn on "Memory saving mode" Tools>Application options>Drawing

We went to xp64 machines for idws and assemblies that size. That will give you a 4gb address space with IV 2008 (not sure about IV 11) Also, IV2009 is native 64 bit which will help quite a bit.

I also make a Level-Of-Detail in each assembly and sub called "Large Assembly" I suppress any hardware and any internal components that I don't need to see in the parent idws. I then define the Large assembly LOD in my top level by setting each sub to "large assembly" .

Each view in my idw has a design view and a LOD (large assembly) set. I try to avoid having multiple LODs in a idw or ipn. IV can get confused and it won't let you save.

Thanks that helps we are actually getting new machines as we speak and that is part of our IT guys questioning is to how Inventor will perform on the 64 bit XP, I think he will install the 64 bit XP. We actually have 2008 ready to install but we were waiting for these new machines. any negatives to going 64 bit XP?
Thanks,

Something to consider, is that IV 2009 with Vista 64bit can support much more ram. Up to 128GB in fact....although the price on 128bg of ram right now is about the same as buying a new car.

IV 2009 is due out relatively soon.

Right now just a handful of driver issues for older plotters etc.

Just going to 64 bit and still using the 1GB ram will give you better
performance since 64 bit is so much better at managing memory, but you
really need to get your new machines stuffed with as much RAM as the bean
counters will allow you to (at least 4GB)

64 bit problems:
printer drivers can be wonky. I can print to pdf from Inventor with Acrobat 8.1 by my co-worker has to use cutePDF.

We use Indesign for parts manuals. It will not run under xp64.

I have to use a 3rd party mouse driver for my wierd mouse that has a xp32 driver.

I can't get firefox to work.
Check all the software and hardware that you want to run. In most cases you should be ok, but if you need somthing critical, you may have to duel boot.
