Project Cooper is a new and user-friendly drawing and presentation application, which should appeal to casual users, people with no CAD background and home-users. But nothing prevents you from trying it out as professional architects. It actually contains enough precision for proper drawing on scale and uses the DWG format for interoperability with CAD software. As most Autodesk Labs projects, specifications and availability are subject to change and no info is given on later possible commercial pricing. Current release expires on April 30, 2010 and available in US and Canada only. Windows XP or Vista (32-bit) are required. More info on http://www.autodesk.com/pr-projectcooper .
