Fatal Errors on Big Files

[Sampdoria]

Hi

[Sampdoria]

Hi,

I'm using a 64 Bit machine with Acad 2008 on it. Im sure its 32 Bit Cad because its installed in the Program Files (x86) Folder.

When my Files get progressively bigger with lots of objects, materials and landscaping trees, of course the file size increases. Usually upto 60-80Mb.

The problem is not that the render crashes - the problem is when I Render/Stop for changes, save, and continue this a few times, Acad eventually  gives me a Fatal error. Any idea why it crashes? Is the memory frozen up or something?

regards

Hi Birdman

Why don't you try to install 64 bit version of ACAD to see if the problem persists? I'd thought when you install AutoCAD (I remember this on my wife's seat from ver. 2010 I think) installer doesn't allow you to install 32bit version on 64bit OS. Of course maybe I am wrong. Take a look on this

It's a limitation of 32 bit systems.  More information is here.

Sure I understand, Ive read the list, but for me the problem is not rendering but in one session, render+stop x 3 and 4th/5th time the file crashes.

Yes George, I have installed the 32 Bit AccuRender on what I suspect is AutoCad 2008 32 Bit - on a 64 Bit System.

How can I figure out if my CAD is 32 or 64 Bit?

Cheers

The memory should stay pretty stable if all you're doing is rendering and stopping-- it still may change a little and if you're walking a tightrope it may put you over the edge.  If you're making AutoCAD changes between renderings the memory allocation will grow.

If it's installed in the x86 folder it's almost certainly 32 bit.  You can also look at the Process tab on Task Manager when acad is running.  If it says *32 after acad.exe then it's 32 bit.

The link I sent you also suggested the 3GB switch if you haven't done so already.

The autocad 2007 with the exe*32 is 32 bit while 2013 with exe is 64 bit.
