Hello Anton and Ecati

Greetings and thanks to you both

Hello everyone

I have a problem with the joint hinge, the stiffness of the hinge is set to 1.000 however the object attached to it moves in the Z-axis as if there was a huge gravity. When the object does not move any more it has returned well in the axis of the hinge.
In advance Thank you for your answers Eric
