auto cad running slow and freezes please help

[Anonymous]

Hi, my auto cad is running extra slow on my macbook pro, mouse takes ages to move, copying and pasting also does too basically everything.

I have imported my sketch up model into the existing dwg drawings and don't know whether this is causing havoc. However, I don't want to wipe everything and start again. 

Is there anyway i can speed things up? 

Please help Im a student and have a deadline to meet. ahhhhh 

excuse the mess.. needs cleaning up

Hi,

At first set AutoCAD system variable CONSTRAINTINFER=0: at the command prompt type CONSTRAINTINFER, than hit Return, than type 0 (zero) and hit return again.

Command: 
Command: CONSTRAINTINFER
Enter new value for CONSTRAINTINFER <1>: 0
Command: 

Now try to open attached drawing.

Does it run better?

I deleted all Parametric constraints in your drawing which I believe are the result of Infer Constraints was turned on in your AutoCAD.
