TYPE: Object State
TITLE: Subnet Operation

The Subnet operation is used to create a new logical grouping of objects.
Subnet objects contain other objects, not SOPs like most object types.  This
lets you organize your object hierarchy.

You select the object that will be used as the parent for the new Subnet
object, and right-click to complete the operation.  There are no handles
defined for this operation.

The operation controls bar above the viewport provides access to the Display
parameter of the Subnet.  When the Display parameter for a Subnet is set to
0, none of the objects contained in the Subnet are displayed.  When this
parameter is set to 1, the Display parameter of the contained objects are
used to determine the visibility of each object.  The operation controls bar
also lets you specify which object\'s transform should be used as the output
from the Subnet.  You can either choose to pass through the transform from
one of the Subnet inputs, or to output the transform of one of the contained
objects.

You can change the Subnet object\'s parent objects any time by hitting the
Reselect Geometry button or typing \'${h.pane.gview.redoselection}\'.  If
Secure Selection is turned off, selecting new objects will immediately
complete the selection and connect the new parents.  Otherwise, you right-click
to signify that the object selection is complete.

If Secure Selection is turned off, you can select any other object in the
viewport.  Doing so will switch to the operation appropriate for that object
type, and the current operation will be exited immediately.
