Multibodies

Multibodies collect and organize ellipsoids, multibody planes, and multibody joints and are typically used in multi-body analysis.

Ellipsoids, multibody planes, and multibody joints can be organized into a multibody using the Organize panel. Every ellipsoid, multibody plane, and multibody joint must be organized into one, and only one, multibody and therefore are mutually exclusive to a multibody. Newly created ellipsoids, multibody planes, and multibody joints are automatically organized into the current multibody.

Operations performed on a multibody collector affect ellipsoids, multibody planes, and multibody joints within the multibody collector. For example, if you delete a multibody collector, the ellipsoids, multibody planes, and multibody joints within the multibody collector are also deleted.
