Point-Point Constraint 753
Properties rollout
Par ent—When on, the constraint has two bodies
and you can designate an object to be the parent
body. When off, the constraint is single-bodied
and the point occupied by the Parent Space
sub-object is the p arent.

Thereafter the button d isplays the name of the
parent body.
Child—Displays the name of the second rigid body
attached to the constraint. You assign the child
object by clicking this button and then selecting a
rigid body from any viewport.
Align S paces To—Use these options to align the
bodies’ local constraint spaces. You can find
out more about each option in Working With
Constraint Spaces (page 2–726).
Lock Rel a ti ve Tra n sf or m —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 and rotates along
with it, and vice-versa.
Strength group
Strength/Tau—Gover n the impulses applied to
the constraint’s bodies in order to maintain the
constraint, and so how strongly the constraint
works to restrict their movement. You can find out
more about these parameters in Strength and Tau
(page 2–735).

•
Standard—The defau lt option.
•
Limited—This type allows you to limit how the
child object can rotate relative to the parent.
•
Stiff Spr ing—This type allows you to specify a
distance for reactor to maintain between the
constraint attachment points.
Limited (Limited constraints only)—Lets you specify
how much the child object can rotate relative to
