Use the Prop erties rollout to edit the properties,
which are described in the Interface section,
following.

Mass—Therope’smassinkilograms.Thisaffects

objects, its buoyancy when interacting with water,
and the stretching caused by attached rigid bodies
(page 2–798): the h igher the mass of the rope, t he
less stretching induced by the r igid b ody.
Thickness—Lets you specify a thickness for the
simulated rope, as the shape used to create the rope
has no inherent thickness. A rope with a thickness
of 0.0 will not be visible in the simulation.
Fr iction —Thecoefficientoffrictionfortherope’s

smoothly the rope will move relative to surfaces
