Hi,

This is my first time posting on this forum, please forgive me if I leave out any critical information.  Here is the situation...

I am trying to create an animation that has only 3 total parts with multiple configurations that move within each other.  We will call them tube, locker, and pin.

Tube has 4 slots in it and when the part is stretched, the locker is able to grap these 4 slots and hold the tube in a locked position.  The pin is what forces the locker into the slots of the tube.

I have 2 configurations of the tube, they are non stretched and stretched.  I also have 2 configurations of the locker, they are closed and open.

My question: Is it possible to have steps where the parts switch between configurations?  Is there anyway to have a smooth transition between configuration changes without creating more configurations between the "static" states?

Any help is greatly appreciated and please feel free to ask any question which may help.
