Help reducing file sizes

All:

I have some imported step files (air cleaners for a vehicle) itruns close to 80MBin size. Is there any way to "dumb-down" the fileto reduce file size. It's running a load of surfaces (moldedplastic with drafts). I have tried setting it to load aslightweight parts but it is still bogging severly.

I am putting three different aircleaners (varying from 50MB to 80MB in size) into a material handling rack to represent them. AfterI do this the model chugs extremely slow and the drawing file seven worse. It took a good 13 minutes to print the sheet set out.(B size drawings with a view a piece, top, right, rear, plan, iso)

Any help would be appreciated!
