Configurable Joint Axes and Spring Behavior When Locked

Hi All,

I was hoping for some help understanding the ConfigurableJoint object.

I'm making a rope directed down the x-axis (1, 0, 0). I have the ConfigurableJoint primary axis perpendicular to the rope (0, 0, 1). The secondary axis is going up (0, 1, 0) and is also perpendicular. Is this correct or should the primary axis aim down the length of the rope?

Also, I've locked motion on all axes yet I still get 'stretch' in the rope chain. The docs say limited uses the limits but locked stops all movement. This is not what I'm seeing. Am I doing this incorrectly?

Any help is appreciated!
