this is the who is the thing when nothing happend.
Now i can do this
But now i want the plate move like on this screen. I can rotate them like on the second screen but i didn t find a good way to reduce space between them like on next screen.
I would like be able to rotate then reduce space and do way back to normal only by moving the right piston in following the Red axe.
actually it s work like that
plate are constrain to rotate like the right one who is aim on the piston.
For limite the rotation a i have constrain the piston to follow a curve (in blue) like that it s working perfectly.
Each plate as is middle axe point on the green curve.
So actually for do the screen i actually move the piston along the blue curve like this i got the Second screen and after i have contrain on scale the green curve to the red one. so i juste reduce the scale. but i would love get the 3rd screen without do the second first...
I join the file if that can help.
