Hello,  
i need to display the vertices- and facenumbers to write a right BlockMeshDict. I have an existing polyMesh and i like to extend it.  
Is it possible to display these values on paraview ?

In a other case i have a stl-File, so i need to display these values aswell.

Best regards  
Kai

- Vertices  
Use the GenerateID filter

- Faces  
There is no such concept in VTK/ParaView. This may still be possible but you will need to specify a litle bit more what you are trying to do.
