How can I fix this issue with a gate?

Hello. I am trying to make a realistic garage gate with prismatic and ball in socket constraints.
When I close the gate, sometimes it collapses. Here’s a demonstration of this:


The gate is pushed with a prismatic constraint and those gray parts are connected by ball in socket constraints.
I tried to set a border part outside of the building, results only get worse.

Select the parts of the garage door and change their friction under Custom Physical Properties to the lowest possible value (0) or whatever fixes the issue. The problem with your implementation is there are no wheels on the segments to reduce the friction between the rails and the door.

You sure that the gate parts all have the same speed ?
If a part dont have the same speed as the others parts then there is a way that the whole gate can collapse :frowning_face:

Thank you! That solved the issue.

You don’t get the construction of this gate. At a top, a single PrismaticConstraint pushes these parts, which are connected by ball in socket constraints. This type of constraint allows movement of connected parts in any direction, while snapping them together. Speed of all parts is the same in this case, because, I repeat, there is a single motor that is moving them all.

I am sorry for wasting your time.
But i am happy that the problem is solved. :smiley:
