Screw thread

ste

New member
Hello,

I've made a corkscrew (see attachement) and I would like to animate it.
However there is a problem: or it doesn't converge or there is a problem with the kinematic constraints.
For the relations in assembly: I've taken an axial align between the long vertical rod and the horizontal rod on top, so four degrees of freedom are removed. Maybe there has to be removed one more degree of freedom because of the link between rotation and translation when using screw thread, but I don't know how to do. Can someone help me?
Thanks.
