AutoCAD 2006, the 20th release of AutoCAD software, increases efficiency with across the board improvements to bring productivity up and lag time down. AutoCAD 2006 is a software to realize your ideas with maximum speed, power, and efficiency. Beginning with dramatically smaller file sizes in AutoCAD 2004, and continuing with the Sheet Set Manager in AutoCAD 2005, Autodesk is raising the bar on productivity once again with AutoCAD 2006. From the new dynamic blocks capability that allows you to quickly create, manipulate, and extract data from blocks, to heads up design, which keeps your focus on your work rather than on the software, AutoCAD 2006 makes an impact on the way you work, every single day.
