I was browsing the Autodesk website today and happened to notice that AutoCad 2005 has been released. Not sure how long it has been out, but I just noticed it. Anyways, I was as to how much of a difference their is between the 2004 edition and the newest edition (2005)? Are the differences and new features significant enough to pay for the upgrade to 2005? I get an academic discount, so price is only a small factor. Any advice or help is greatly appreciated.
