In the modifier stack open the dashpot’s
sub-object list.

the object in whose space you want to move
the attachment point: Parent Space or Child

viewport and can be move d using the Move
tool. The attachment point maintains its
position relative to its corresponding object; for
example, if you move the child object, its space,
and hence its attachment point, moves with it.
The attachment point doesn’t have to actually
be on either object.
