Help with simple telesopic joint example


I could use some help with a simple IK setup. I am trying to set up multi section telescopic mechanism. But for whatever reason I am not doing it correctly. An example with 3 or 4 nesting / telescoping sections would be helpful.

Something like this?

Beautiful example. Thanks. The tripping point for me is the last section of
the telescope. If the motion desired is a simple linear move I try to just
animate the last section and expect IK movement of the rest of the chain.
But it needs the constraining object at the end.

Many Thanks,

Right you are. Moving the last section will only make it move away from its parent.
Maybe take a look at the video on our website Around min 1 the “generation gap” is illustrated.

When you just need a linear movement obviously you can replace the curve by a point and let it simply move up and/or down.
