I especially would like to thank my wife Dixie for putting up with my schedule and being a “single parent” when things got really busy for me.Įric Chappell has been working, teaching, writing, and consulting in the world of civil engineering software for more than 20 years, and he is a recognized expert in the world of Autodesk® AutoCAD Civil 3D® software. To Joshua Modglin, thanks again for giving me the peace of mind of knowing you had my back on theĪnd to my family, for putting up with a fourth year of Dad working late nights and being distracted and sometimes stressed, and for all the other not-so-fun aspects of having an author in the family: thank you. To Kim Wimpsett, thanks for putting up with me and making the book better than I could have ever made it myself. To Pete Gaughan, kudos for taking the reins and being a great coordinator, sounding board, and go-to person. To Willem Knibbe, thanks once again for making the book happen. Of course, I’m just a small part of the book’s success, and it would be a terrible disservice not to mention Wiley/Sybex for giving me this opportunity yet again, and its great people for helping make the book a success. Every year that I get to work on another version of AutoCAD® Civil 3D® Essentials is a blessing, and this year is the fourth! I am very encouraged by the emails I get from readers throughout the year, asking questions and offering suggestions, and I especially like those that compliment the book.
