Separates the current group into its component objects or groups.
The Ungroup command ungroups one level, unlike Explode, which ungroups all levels of nested groups.
When you Ungroup a group, the objects within the group lose all group transforms that were applied on nonzero frames, but they retain any individual animation.
All ungrouped entities remain in the current selection set.
All components of the group remain selected, but are no longer part of the group. The group dummy is deleted.
