[Gmsh] line loop

[Ronan GUENANFF]

hello,

I am trying to make a line loop with two line arrays
the union of which constitute a whole line but
the order of the sublines is not respected in the arrays.
"Line Loop is wrong"
What is the symptom of this error?

I also tried with a unique array where the order is not
respected either, but it still produces the error.

Do I have to order my array with continuous sublines?

Thank you for responding,

Best regards,

Ronan Guénanff.
