Week 3 - Spinny, turny and suspension

First of all we need to create groups for the spinning and turning,

then control arrow. I used EP curve which I have bent. The key for a good bend is to make point every grid square.

Okay, all is ready for spinning the wheels. We need to make sure that the transformations are frozen and the pivot centered. When all that is done, we select the arrow, then the wheel, go to Constrain→Orient an we need to make sure that we selected the right spinning axe, in this case X.

Then we click Apply and Add an it is done. Eppur si muove!

Now we need to do the rest of the wheels. Front and rear wheels should have separate arrow.

We do the same for the turning, but the constraint axe will be Y. 

Tadaaa!

The last thing is adding the suspension. We need to create NURB circle, put it under the wheel and then just assign Point constraint in the Y axe.
