Reddit reviews Beginning AutoCAD 2018: Exercise Workbook

Lynda.com is, again, a wonderful resource. Pick any of the "AutoCAD 20XX Essentials" courses for the version you'll be working with and you should be good for the basics.

I've been using AutoCAD on and off again for ~10 years and first started learning it back in high school and learned most of what I know now either on the job or taking taught classes. However, my boss had to learn AutoCAD by herself and used these and has told me they're very helpful to learn, she refers to Shrock's little reference guide book from time to time still. That Shrock is pretty much the standard when it comes to AutoCAD teaching material, or so I'm told. I've looked at the book and it seemed easy to follow and informative and should give you a good grasp of the basics.

Same thing goes for AutoCAD though: use the tutorials to learn the basics but the real learning and knowledge comes from either doing real projects for a job or trying to emulate one. Real life is the best teacher, always. You'll run into all sorts of weird edge cases that really make you get under the hood and learn.

AutoCAD is easier to use, believe it or not, imo, because it tries a lot less to "help" you do things. It really is a blank canvas and allows you to do whatever you want. That's also what makes it challenging to use though for people who are used to Revit and all of the "hand holding" it tries to do for you. Revit is very good at what it does but outside of that it's rough. AutoCAD is OK for a lot more things but you have to do a lot more of the work yourself (for example, the differences between how Revit and AutoCAD do dimensions and scaling, layouts vs views, that sort of thign). Anyways, enough of my ramblings, good luck!
