Fatal Error: Out of Memory

[gibbsml]

I am trying to make an array of 3um circles separated by 10um over 9 square inches using the 2008 version. I choose to use an octagon and then converted it to a block so now the file size is manageable. I have been using the MInesert command to build my array of blocks but before I even get a quater of the area covered my computer says it is out of memory (this happened on Vista and XP). I can't even run autocad more than a couple of minutes after I open this file. How can I build this array without using so much of my RAM?

First, welcome to CADTutor.

Second, post the specs on your computer setup. It would help to know how much memory (RAM) is installed.

I have a HP Pavilion with duel processors and 3G RAM but with Vista I have just over 1.5G of RAM available when autoCAD is running. I did what I could to maximize the free space but it wasn't enough.

I also try to make the same design as gibbsml and obtain a "run out of memory"
my specs: XP pro version 2002 service pack 3
intel(R) core(TM) 2 duo cpu
E8400 @ 3.00GHz
2.99GHz, 1.94GB of RAM

what can I do to continue my design???

thanks,
