Update: In September 2010, the DWG file was replaced with an updated ribbon reference file.

Tipster Julia Noble shares an AutoCAD file she created to help find commands in the AutoCAD 2010 ribbon.

"I'd like to share this ribbon menu and use it as support information. I created this file when I got AutoCAD 2010. It helped me to learn the new features of this version more quickly, and I hope it will help new users of AutoCAD 2010 too."
 
Notes from Cadalyst Tip Patrol: Julia put a lot of work into this ribbon map. I didn't verify all the command locations on this map, but it seems to be correct. Keep in mind that it only pertains to the unmodified AutoCAD 2010 ribbon. If you are using AutoCAD 2009 or AutoCAD 2011, the out-of-the-box ribbon is different. And if your ribbon has been customized, this won't work for you either. This reminds me of a CAD drafter I worked with that drew every icon of the new toolbars when we switched from AutoCAD r12 DOS to AutoCAD r13 Windows!

If you can't find a command in the ribbon, you can search for it in the Application menu. Type the command in the search box of the Application menu (the big red A), and AutoCAD will list where you can find the command. It also provides the command; all you will have to do is click on it there. If you still can't locate the command, you can always type it on the Command line. Type in the first letter of the command, then press Tab to toggle through all commands that start with that letter until you find the one you want.
