Best Place to Learn Inventor

[David]

Hello. I am trying to learn how to use inventor, but unfortunately no one else on my team has any experience with the program. I can already do most basic features, like assemblies and parts, and have designed a precise chassis, but i am at a lose for any of the more complex features like bolted connections, weldments, and stress analysis. Is there any place where i can get tutorials on advanced features. Thanks in advance for any help.
