How can you constraint the movement of an object? In my case, I want an object to rotate only on its x axis. I’ve tried to apply constraints to the object, but I cannot figure out how they work. The wiki site is down and the books I have (Essential Blender and Introducing Character Animation with Blender) only offer information about applying constraints to armatures.
I’m modeling a simple machine. It does not deform, so I’m not rigging it. However, it has a few moving parts and I want to limit the movement of those parts, but cannot manage to intuit how to do that. It’s a simple parent-child relationship – like a wheel spinning on an axle. I just want the wheel to rotate on one axis.
Sorry for such a noob question, but I’ve looked everywhere I can think of for an answer.
