3-Jaw gripper

How do you get all the fingers of a 3-jaw gripper to actuate using the modelling feature? The first one is easy, as it is aligned with one of the axes. However, as the other two don’t line up, I’m unable to get them to follow the first one properly.

You can move and rotate the node origins by setting the Move Mode setting in the modeling tab from Hierarchy to Selected.
This allows you to rotate the axis so that it is facing the correct direction and you can configure the follower joints.
