Help with constraints

[nathn123]

Hi i was just wondering if someone could confirm something for me, with constraints is the frame in transform the ;

direction vector to the other object i.e A - B
or is it the direction to the constraint
or is it the position of the other object

Thanks in advance

The frames are the transformation to the constraint axis in the local coordinates of the bodies involved (frameInA is from A to the axis in terms of A, frameInB is from B to the axis in terms of B)
