While we're on the topic of hierarchy, I'm in a bit of a rut myself.
The central axle is rotating. While it is rotating, I need it to move in and out the x-axis as seen below.
My problem comes as I imported the model from Inventor, (so it is a mesh) and need the circle to stay a set distance above the edge of the stationary object. So, I would like the circle to be always x unites away from the edge (represented with the line with arrows). Can this be done hierarchically, or must I manually do this through the graph editor?
