Getting Information Fast

I've included plenty of tips and warnings:

Tip  

Tips are designed to make practice easier.

Warning  

Warnings steer you away from pitfalls.

Also, in each chapter you will find more extensive tips and discussions in the form of sidebars set off from the main text. To encourage you along the way, some of the sidebars show you how topics in each chapter were applied to a real-world project, the San Francisco Main Library. Together the tips, warnings, and sidebars provide a wealth of information I have gathered over years of using AutoCAD on a variety of projects in different office environments. You might want to browse through the book, just reading these notes, to get an idea of how they might be useful to you.

Another quick reference you'll find yourself turning to often is Appendix C, which contains tables of all the system variables and dimension variables with comments on their uses. If you experience any problems, you can consult the "When Things Go Wrong" section in Appendix B.
