[Paraview] Unstructured Grids with Zones

[SamuelKey]

Terry,

I have had considerable success using the EnSight reader in paraview and 
"breaking" my data into EnSight "parts."  PV has a filter called Extract 
Parts that, in essence, gives one the ability to turn freely each part 
on or off for viewing.  I also double check the correctness of my 
boundary conditions which are applied either to point-sets or to 
surface-facet-sets by making each one a "part."

They have an internal mesh, boundary meshs(consisting of faces), and face/point/cellzones  (made up of subsets of the mesh).  so I need to create an unstructured grid that has regions/zones, would be best if each region could be toggled on and off, so the user could view all the regions or some of the regions...etc.  could someone point me in the direction of the class I should be using to do this?Thanks in advance.
