Once created, a Slice object is added to the Browser.  Selecting it from the Data Tree will show its Name, # of Levels and # of Open Curves (if any) as well as the entire model extents (Box, Lengths and Center) in the Information Window.  

If ANY open curves are generated, the icon is displayed indicating that your mesh is NOT closed.  If the mesh is closed, the icon is displayed.
