How to convert the Block Number to attribute for each point?Thanks

GenerateIds should do the trick

Thank you, but I’m referring to the Block Number, not the point ID.

Indeed, the to use filter is named “BlockIds”

I can’t find this filter “Block ids”

Which version of ParaView are you using ?

pv 5.6

This filter probably does not exists with ParaView v5.6, please update to the latest release, you can find it here: https://www.paraview.org/download/

ok, I’ll try, thank you.
