Although it’s not officially supported, it can also run in Windows XP Tablet 
2005 Edition and make use of the tablet functionality included in Windows 
Vista and Windows 7. Trying to do production drafting on a tablet isn’t a 
great idea due to limitations in the graphics system, but I know it works, 
because I’m running it that way myself!
Because of AutoCAD’s MS-DOS heritage and its emphasis on efficiency for 
production drafters, it’s not the easiest program to master, but it has gotten 
easier and more consistent over the past decade or so. AutoCAD is pretty 
well integrated into the Windows environment now, but you still bump into 
some vestiges of its MS-DOS legacy — especially the command line (that 
text area lurking at the bottom of the AutoCAD screen — see Chapter 2 for 
details). But even the command line — oops! command window — is kinder 
and gentler in AutoCAD 2011. This book guides you around the bumps and 
minimizes the bruises.
Why AutoCAD?
AutoCAD has been around a long time — since 1982, which I suspect, dear 
readers, is longer than some of you! AutoCAD ushered in the transition from 
really expensive mainframe and minicomputer CAD systems costing tens of 
thousands of dollars to merely somewhat expensive microcomputer CAD pro-
grams costing a few thousand dollars.
AutoCAD’s 3D abilities have grown by leaps and bounds over the last several 
releases, and 3D modeling is becoming a common way of checking designs 
before they’re drafted. Nevertheless, AutoCAD is, first and foremost, a pro-
gram for creating two-dimensional technical drawings: drawings in which 
measurements and precision are important because these kinds of drawings
