Damping The damping value of the suspension spring. Higher values suppress
vertical oscillation. Available with Havok 3 only.
Spin Parameters group
Velocity This value indicates the angular velocity in radians per second that
the constraint will seek to achieve for the wheel.
Gain This value indicates the maximum angular impulse the constraint can
apply to attain the specified angular velocity.
Breakable group
Breakable When on, the constraint is breakable. If its breakable limits are
exceeded during simulation, it ceases to exert impulses on the attached objects.
For more information, see
Breakable Constraints on page 3944.
Display group
Size Lets you change the size of the constraint space display in the viewport.
Reset Default Values Returns the constraint's parameters to their default
values.

The Point-Path constraint allows you to constrain two bodies so that the child
is free to move along a specified path relative to the parent. Alternatively, you
can create a single-bodied version of the constraint, where the constrained
body can move along a path in world space. The child body's orientation is
not restricted by the constraint.
You could, for example, use a Point-Path constraint to simulate a bead on a
wire. In most cases, you don't need to specify a parent rigid body for a
Point-Path constraint, unless the motion of the path itself should follow
another rigid body.
