what type of constrain should solv the problem?
show user profile  talR
I have a machine animation sequence
3 parts:
top object is a tray that moves up and down
bottom object is a curved arm that rotate on z axis where the top age of the arm is actually moving
up or down
and the middle object connects the arm and the tray
so when rotating the cureved arm on the z-axis clockwise the tray goes down
some thing like this:

how do i create this sequence what type of constrain shold i use

forgot to mention
the tray can only move up or down
the bottom object the curved arm cam only rotate on the z-axis
and the middle is like a chain connects both parts

Grotey it's simple, he needs the top bit to fluctuate at a degree multiplied by the z axis rotation of a curved arm rotating primarily clockwise while retaining the intricate depth of retail markets globally that are balanced somewhere in the middle and can only move side to side while transcending with the motion of a mountain lion falling from the top of a bouncy castle.

i tred link constrain but the tray rotate as well
also take in mind that the middle part also rotate when it is connecting the 2 parts
like a chine stuff

So the part in the middle (3) stays vertical at all time?
If so, link 1 to 3, then 3 to 2 and, with 3 selected, go to hierarchy panel > link info and disable inherit rotations.

If 1 is supposed to follow a straight vertical line, then google for piston rig (as in steam engine piston).

Cant imagine 3 stays vertical at all times. just use a simple HI solver
