Parent When on, the dashpot has two bodies and you can designate an object
to be the parent body. When off, the dashpot is single-bodied and the point
occupied by the Parent Space sub-object is the parent.
You assign the parent object by clicking this button and then selecting a rigid
body from any viewport. Thereafter the button displays the name of the parent
body.
Child Displays the name of the second rigid body attached to the dashpot.
You assign the child object by clicking this button and then selecting a rigid
body from any viewport.
Align Spaces To Use these options to align the bodies' local constraint spaces.
You can find out more about each option in the
Working With Constraint
Spaces
on page 3928 section.
Lock Relative Transform When on, the relative transform between the child
and parent constraint spaces is locked: If you move either space in the viewport,
the other space moves along with it.
