Learning Center tutorials

Still trying to get used to sketch up and find my way,

I am working through the tutorials and have grasped the basics of drawing things (i hope ) .
my goal is to be able to draw machine parts and the assemble the parts and see if they fit similar to inventor.

I am looking for more tutorials , i can draw a part ok so where do i go next ? do i make this a component ? and then draw another and assemble them together ?
