This site provides great tutorials / lessons for the student of AutoCAD. These lessons are designed to be as compatible with as many versions of AutoCAD as possible. They are based on AutoCAD 2007, but can be easily adapted to other versions. The lesson format was used in my CAD classes I have been teaching previously. Any feedback would be used to make these as useful as possible. Please note that these lessons are for private, individual use as well as public schools.
