Dear Christophe, Thanks again: yes, obviously I have that option too, but I don't see any duplicates when I merge the file. The duplicates appear after I create a surface loop. That is what I was trying to say from the beginning. I tried to be sure of that before sending my meesage, so that is why I used a very simple model.
