Solidworks trail version

Does anyone know of a solidworks trail version i can get a hold of.  I have a friend that is teaching a class at a college, and he would like to do some of he's homework at home.  Or maybe a viewer that shows features of how he part was made.  Edrawings is good, but doesnt show how a part was made(not that I coud find)

Thanks in advance!
