I,m using AutoCad 2011 with a new 64 bit 32 gig computer with Quarto 4000 video card. I imported a CadWorks drawing that is 18,500 KB in size and my computer moves it in CAD supper slow. Is there something that I can do to help it are this is how it is going to be?
>> I imported a CadWorks drawing
What object-types are these objects you imported?
Is it only command _MOVE that works slow (have you tried it with OSNAP turned OFF for test)?
Or are other commands also slow, if so which one?

>> They are 3D items that were imported
Surfaces, or 3DSolids, or 3DFaces, or extruded Lines/Polylines/Splines, ....?
>> Most of the commands move very slow like ZOOM ROTATE and others.
What visual style is active?
Have you tried to play with hardware-acceleration?
Do you use the nVidia Performance-Driver?
What do you want to do with this geometry, why do you change to AutoCAD?

sometimes when you import your 3D solids from other type of application they can consist of too many parts - that will slow you, try to UNITE those parts as much as possible, thus you will have less items in your file. And try to use wireframe as much as possible.
As in, CADWorx Plant? 18000 KB CADWorx models are going to be slow no matter what you do to that one file. Best option is to break it down into multiple models and XREF them together as needed. If you have a slow-to-mid speed processor (basically, anything less than 3 GHz) that's not going to help either.
I don't think that CAD 3-D is made to handle such a large file.
"AutoCAD" doesn't like files large, but other CAD software can do just fine, ie, Inventor, Pro-E, etc.
