Hi guys, I've become interested in learning a little more about the third dimension, so I "bought" Autodesk Alias ​​Automotive V.2012, but I have big problems getting started!

Does anyone have any good tips or tutorials?
NOTHING is like photoshop, which I thought ....

I've tryed to make a wheel, but even after a couple of tutorials on youtube so I have not managed to make the wheel round!? : S

I'd appreciate all the help I can get and hopefully it can help someone else with the same problem!
