Check this box to allow region objects to produce new objects for each exterior boundary polygon contained in the region, and retain any holes (interior boundary polygons) within the exterior boundaries. If this box is not checked, all polygons contained in the original region will produce separate Region objects, regardless of the interior/exterior boundary designation. Holes will become solid polygon regions, and no output region object will contain any holes.
Polyline objects will be disaggregated into multiple Polyline objects for each section of the original object. MultiPoint objects will be disaggregated into multiple Point objects for each node contained in the original MultiPoint object.
