Insufficient memory with 512 megs of ram?

[Anonymous]

I am using AutoCAD 2000i with Windows XP. I have 512 megs of ram and the
swap file is set for 768-1536 megs. There is not much running in the
background (Norton Antivirus etc). I tried to open a large drawing file 160
megs and got an Insufficient Memory message. I pretty sure that I'm not out
of ram. Any suggestions?

Thanks
Bob

How much hard disk space do you have on the drive where the temporary
files are saved?

Bob- I use the following rules-of-thumb (not scientific, just what seems to work for me).
1) set your swap file size so it can get as large as 3.5 times your physical RAM size (1792 for you)
2) make sure you have a MINIMUM of 700Mb of free space on your primary partition.
3) Delete your temporary autocad files. If you didn't change the location, they will be in Documents & Settings\your profile name\Local Settings\Temp. 'Local Settings' is a hidden folder.

I hope this helps.

Hi

My experiments show that a drawing used between 6 and 9 times as much memory
as the size of the drawing file. When the file swapes out to disk it may use
even more disk space.

Therefore a 160 MB drawing would require between 960 and 1440 Mb ram and/or
HDD space. so one would assume that you should be OK.

You might like to do a Partial Load if your drawing setop will allow this.
This allows you to open only selected layers and views. ie. it does not load
the entire drawing into memory.

To partially load a drawing, click on the arrow next to the open button in
the Select file dialog (File, Open) and select Partial open. Layers can be
loaded and unloaded using the "Partiaload" You might like to break this
drawing up into layers or tiles and use xrefs.

If you are using this drawing as an xref, look at "Using demand load" in
autoCAD help. Although this requires you to be able to open the file so that
you can save it with a layer and spatial indexes.

Try typing recover in a empty drawing as the drawing you are trying to open
may be corrupt.

Hope this helps.

One more thing - if there are several paperspace view tabs, you may want to
go to TOOLS>OPTIONS and click on the system tab. There is a radio button
that can be set to cache all active viewports. Change to the radio button
for no caching. If it is on, the memory requirements will be many times
greater when switching viewports.
