Hi, friends. who can help me solve this zone name problem. Why the name is changed from '200' to '200_0'? How can I keep it same?

@ha2175li-s If you have 5 thermal zones, you should input 5 names for zoneNames.

Yes. I named them as 100 (one zone but 2 breps), 200, 300 and 1000. When I have more than one brep in a thermal zone it works fine but when i have only one brep it adds _0 to the given name. This creates a problem later in my script.

Is there a way to remove the underscore from the name?

@zahabia, can you upload the script?
