Automoblox CAD Drawings

I got as far as the second model(Figure 1), but I did not complete it. I completed Figure 2 with some difficulty, and overall it was a learning experience.

I most struggled with the unintuitive controls and contexts of Inventor, and its various idiosyncrasies.

What was easy for me was everything else-it was, complications aside, fairly straightforward.

The only thing I would like is more time on Inventor so that I can get used to its control scheme.
