"More than enough" means 1 GB? 2? 3? 4? 32? 64?
And your "machine" is a Commodore 64? Apple II? Mac SE30? Pentium 1?
Operating System is... Mac OS8.6? Dos 3.0? Unbuntu? Windows Vista? XP?
Objects being altered are 3D objects? Raster photos? Type? Flat Shapes?
No one can help at all if you don't provide even the basic information.
4GB of RAM is the base anymore. Since Illustrator is a 64 bit application, and your running a 64bit OS, you can take advantage of much more RAM.
That being posted, it's difficult to say if more RAM would help your issue. You still have yet to provide any information on the actual artwork. Again.... no one can help unless you first provide detailed information.
Hello again Gentlemen.
I had opened yesterday photoshop and illustrator,photoshop file is: 4000pixels by 2000pixels 72ppi.
when ever i was trying to do something in illustrator with 3d i would get the message:Operation could not be complete because there isnt enough memory RAM etc etc.
But then when i closed photoshop,and only illustrator was running, the 3d was able to work in illustrator.so once the object was created i then opened photoshop and copy/paiste onto the artboard.
so this means that photoshop is using more CPU memory?causing the programs to not perform?
