SolidWorks will become the industry standard in 3D solid modelling. It is important to learn the fundamentals of this software in a structured fashion such as getting tutorials. Trying to learn it intuitively in the initial stages especially will frustrate you and cause you to develop bad habits. Start as you mean to go on. Try the site mentioned above. They are written for students and appear to assume no previous knowledge for the initial modules.

Do you have your own copy of Solidworks?
If so there's plenty of online video tutorials (SolidProfessor and CADJunkie is meant to be good, there's plenty others out there too).
Draftsight is a similar program to AutoCAD and it's free so you can try that.
