Dedication

From Lee: To Kristina, Isaac, Amber, and Chloe; my wife and lovely kids for
hanging in there during the long hours I was working on this book. I also canít
forget everyone else who has had some influence on my career, through both
the good and the bad.
From Dave: To Anna and Delia, the two women in my life, who remind me
there are other things besides keyboards and mice (and sometimes they have
to try REALLY hard).
Authors Acknowledgments
Lee Ambrosius: I have to give a special thanks to the great folks at Wiley for
being supportive through this entire project and giving me this opportunity.
Next, I want to thank David for letting me be a coauthor on this project.
Moving up from technical editor to coauthor was a big step ó thanks for
giving me the chance. The next two people were very inspirational on this
project and helped keep things moving along: Colleen Totz Diamond and
Tiffany Franklin. I think we made it.
Thanks to Shaan Hurley, Bud Schroeder, Kelly Miller, and the other great pro-
fessionals at Autodesk for taking the time to answer questions as they came
up during this project. Last, but not least, thanks to our technical editor,
Mark Douglas. Mark is most definitely not a stranger to AutoCAD; he is blazing
his own trail in the CAD community as a respected individual who is always
willing to help out a fellow user in need.
David Byrnes: Thanks to Mark Middlebrook for bringing me aboard the
Dummies train and for collaborating on the initial proposal and table of con-
tents for this book. Thanks, also, to Lee Ambrosius for joining up in the bookís
darkest days and for picking up more and more of the project as time went on.
Thanks, too, to colleagues and friends at Autodesk ó Shaan Hurley,
Nate Bartley, and Bud Schroeder ó who never seem to mind being asked
even the dumbest questions.
At Wiley, thanks to Terri Varveris, who got the project off the ground, and
Tiffany Ma, who shepherded it through with enthusiasm and an unbelievably
awesome degree of patience. It was also a great pleasure to work with project
editor, Colleen Totz Diamond, who deserves medals for patience and diplomacy!
And by no means last (someone has to bring up the rear), thanks to
Mark Douglas for taking on the tech editing job. Markís expertise and enthusi-
asm are well known and respected in the AutoCAD community, and weíre
delighted to have him with us.
