Does anyone know a good place to do Ifeatures and Iassemblies?

I am trying to learn how to do these and want to learn them for future knowledge. I am a Laid off casework engineer and would like to have my own library built so i can do high end drawings for customers and not have to draw each cabinet from scratch. I have inventor 2012 and would like to have some skills caught up to current. I tried looking for them but some of them were out of the water and looked to be for later down the road. I am looking for simple and easy so i can get the concept of it first.

I am still reading more on there but i was wondering if there was some external sources to check out that would show how to do more and break it down in different classes, Like for casework and all that.
