AutoCAD is more then adequet for making schematics and layouts. Since ACAD-E is many thousands of dollars, is it really needed? There are many links listed on this site, just click the "Search" tab above.
My AutoCAD training consisted of:
1) Click number 3 on menu to go to autocad.
2) Click on Autocad to start program.
3) Control C will back you out of whatever trouble that you just got into.
I made my own blocks and symbals at first.
Being a hacker, I got through the first day. I did have a big set of ACad manuals on hand, though they were an older version. I made several drawing that first day, and "scaled" them. The next morning, after reading some of the manuals, I found out that I should be drawing "full size".
I went to the library and found some pocket guides and other books on AutoCAD, and learned lots of shortcuts.
The pocket guides were lifesavers, and big timesavers. Perhaps one of your area libraries or bookstores has something available.
I have seen AutoCad for Dummies, but can't remember if I thought that it was extremely Good or Bad.
I've never looked, but maybe there is a "ACAD.NET" site out there, like PLCS.NET.
