Ellen Finkelstein

To MMY, for teaching me that there’s more to life than meets the eye and that the deeper levels of life are the most intelligent, powerful, and blissful.

To Dawn, my favorite and only sister, for being there over the years and encouraging me to dream big.

About the Authors

Ellen Finkelstein learned AutoCAD in 1986 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 website creation and Internet marketing. Her website,, contains tips and techniques for AutoCAD, PowerPoint, and presenting, and she publishes the AutoCAD Tips Blog and the AutoCAD Tips Newsletter. Ellen has written extensively on AutoCAD, including articles for Autodesk’s website and features for AutoCAD’s Help system. Ellen's first book was AutoCAD For Dummies Quick Reference. Since then, she has written books on PowerPoint, ( For Dummies), Flash (including Flash CS5 For Dummies), and web technologies (Syndicating Web Sites with RSS Feeds For Dummies). You’re holding the 14th edition (wow!) of this book, which previously appeared for AutoCAD releases 14, 2000, 2002, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, and 2013.

Lee Ambrosius first started working with AutoCAD R12 for DOS in 1994. As a drafter, he quickly discovered that every project included a lot of repetition. Lee, not being one to settle for “this is just the way things are,” set out on a path that would redefine his career. This new path would lead him into the wondrous world of customization and programming — which you might catch him referring to as “the rabbit hole.” As a self-taught programmer, Lee learned to write AutoCAD-based programs in AutoLISP, VBA, ObjectARX, and Managed .NET. After a few years of absorbing content, he decided to give back to the community that helped him expand his career. Lee first started writing his own articles on his website ( before writing articles in AUGIWorld and HotNews for AUGI ( He has also been working on the AutoCAD and AutoCAD LT product documentation since the 2007 releases of the products. Around 2006, Lee became interested in working on books and has been involved in various editions of the AutoCAD and AutoCAD LT Bible, AutoCAD For Dummies, AutoCAD & AutoCAD LT All-in-One Desk Reference For Dummies, AutoCAD 3D Modeling Workbook For Dummies, and Mastering AutoCAD for Mac as either a technical editor or author. His most recent book is AutoCAD Platform Customization: User Interface and Beyond.
