In addition to @Tricotou ‘s answer you can specify directions when creating the line in ribbon mode. Your PG with the flat array points should work with the direction specified.

General advice:
Don’t use Vector3’’s when specifying the points array unless you really need to. Use plain numbers. Vectors are converted to numbers anyway when creating the line mesh.
