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, and she publishes a monthly AutoCAD Tips Newsletter. Ellen has written extensively on AutoCAD, including articles for Autodesk's Web site, such as three white papers on dynamic blocks, and features for AutoCAD's Help system. She is also the editor of Inside AutoCAD, a monthly newsletter published by Eli Journals. Ellen's first book was AutoCAD For Dummies Quick Reference. Since then, she has written books on PowerPoint, OpenOffice.org ( OpenOffice.org For Dummies ), Flash (such as Flash CS3 For Dummies ), and Web technologies (for example, Syndicating Web Sites with RSS Feeds For Dummies ). You're holding the ninth edition of this book, which previously appeared for AutoCAD releases 14, 2000, 2002, 2004, 2005, 2006, 2007, and 2008.
