Restrict motion in 6-dof to rotation
 
Hi!

I am modelling a box being hit by waves. The box is hanging in the air and has a "wire" sticking out of its top, which is actually a rectangular stripe. Now, I want to use 6-dof to check out the boxes and wires motion, but I need to restrict the motion to rotation around the end of the wire, i.e. around a fixed point.

Is it possible? Should I use custom rotation matrices in the UDF?
