Windmeter

I'm very new to CAD and I've been experimenting with autodesk inventor for the past 4 months. I try to create my own exercises, here's one that challenges my assembly constraint skills, along with my first iLogic elements (the bolts are standard in the inventor content library), and the shaft was also generated by itself. Perhaps i will design a gearbox with a dynamo for it after i figured out how to work with the rest of the tools... Wish me luck!
