This will be true of almost any CAD program (AutoCAD may be an exception). If you do any serious CAD with larger assemblies, you're going to need a whole lot of RAM (and a nice screen....). Handliy, RAM is easy to upgrade. Drop in a few gigs and as long as you aren't running on ancient hardware, you should be okay.
