Ellen Finkelstein learned AutoCAD in Israel, where she always got to pore over the manual because it was in English. After returning to the United States, she started consulting and teaching AutoCAD as well as other computer programs, including Microsoft Word, Excel, and PowerPoint. She has also taught courses on Web writing and usability. Her Web site, www.ellenfinkelstein.com, contains tips and techniques for AutoCAD and PowerPoint. Ellen has written numerous articles on AutoCAD and PowerPoint. Her first book was AutoCAD For Dummies Quick Reference. Since then, she has written books on Word, PowerPoint, OpenOffice.org (OpenOffice.org For Dummies), Flash (Flash MX 2004 For Dummies), and Web technologies (Syndicating Web Sites with RSS Feeds For Dummies). You’re holding the sixth edition of this book, which previously appeared for AutoCAD releases 14, 2000, 2002, 2004, and 2005.
