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 constraint.
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
Working With Constraint Spaces
on page 3928.
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 and rotates along with it, and vice-versa.
Strength group
Strength/Tau Govern 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
on page 3944.
Limited group
Limited When on, limits the movement of the child object along the sliding
axis; the child object can move relative to the parent only within the range
specified by the Min Limit and Max Limit values. You can also specify a Friction
value for a limited prismatic constraint.
Min Limit The minimum distance the constraint allows between the two
spaces. For example, if Min Limit is –5.0 then the child body then the child
object cannot move more than 5 units backwards relative to the parent along
the sliding axis.
Max Limit The maximum distance the constraint allows between the two
spaces. For example, if Max Limit is 5, then the child object will not be able
to move more than 5 units forward relative to the parent along the sliding
axis.
Friction The level of friction applied to the objects as they try to move along
the sliding axis. It is applied only to limited Prismatic constraints.
