Re: How could I learn AutoCAD?
 

While a book or a tutorial will help you learn the software, it never quite covers everything. Therefore, i would strongly recommend taking either a class at your school (my school has a three year course in AutoCAD) or take one at a local community college. My teacher doubles at a local college with an AutoCAD class there, so there are classes out there. While expensive, they are worth it for the knowledge you gain from the class.

I agree, the class will probably help also. I was just trying to get our tutorials some exposure. :)

Re: How could I learn AutoCAD?
 

85% of what i learned in autocad, inventor, VIS, 3dStudio Max, Rhino, ETC is self taught, the rest i learned from doing online tutorials or the slight bit i learned from doing tutorials out of the manuals.
Start playing around with it, its tricky but once you get the ball rolling it gets alot easier. I first started teaching myself autocad when i was 10 and my step brother brought a copy home from school and installed it on our home PC, blew my mind then.
To paraphrase the magic school bus "get dirty make mistakes, blah blah blah".
