Used Autocadds
John,
You can't do that. When you purchase (let's say) Release 10 and
then Autodesk upgrades to Release 11, you don't "buy" a new copy of AutoCAD
keeping the old one, you "trade it in" so to speak (upgrade). If someone
does try to sell you an older release, your both breaking the law. By the
way its AutoCAD not Autocadd. Nothing personal, that just a pet peave of
mine. The Intergraph people around the office here do that and it peaves
me off.
