Boudary condition file : 2 2 2 between 5 4 4

@jean-marie.kerloch Maybe more my fault because I use snapping the wrong way ?
Instead of having 5 4 4 on 6 nodes for instance:
2 2 2 ...
5 4 4 ...
5 4 4 ...
5 4 4 ...
5 4 4 ...
5 4 4 ...
5 4 4 ...
2 2 2 ...
I have:
5 4 4 ...
2 2 2 ...
5 4 4 ...
5 4 4 ...
2 2 2 ...
5 4 4 ...
