Copying all subobjects

The given mode is intended for copying all subobjects (islands), available on polygon object to another object. For copying it is necessary in the beginning to select an object - source (object, for which one will be taken its subobjects for copying to another object), and then object - receiver  (object, in which one these subobjects will be added).

The object - receiver before execution of operation can already have subobjects (backed up are added to already existing). To cancel operation, use One step undo mode or Undo item of Edit menu.
