Kubotek Forum

I am trying to get my head around KC Animation, so umbelieveable complex and not proper help or exercises of how to create a hinge.
Where can I find a clear explanation about how to create a hinge, why cannot I simply mate two holes (or axis, or hole faces). Where does collistion come in, what is the exact meaning of collision.

There are several nice examples on YouTube, but none explain the making of it, only showing value changes in the tab.

Any help is much appreciated
