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 Hinge. 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 rotation about the hinge axis between the
attached objects. When this value is true, the child object will only be free to
rotate relative to the parent within the range specified by the Min Angle and
Max Angle values. You can also specify a friction value for a limited Hinge.
Min Angle The minimum rotation the constraint allows between the two
hinge spaces. For example, if Min Angle is –5.0 then the child body cannot
rotate more than 5 degrees counter clockwise about the hinge axis relative to
the parent body.
Max Angle The maximum rotation the constraint allows between the two
hinge spaces. For example, if Max Angle is 5.0 then the child body cannot
rotate more than 5 degrees clockwise about the hinge axis relative to the parent
body.
Friction The level of friction applied to the objects as they try to rotate about
the hinge axis. It is only applied to limited Hinges.
