Hi @lautarolzl,
It is a bit tricky to see what your issue is here but if Patchy's guess is correct then I suggest also to use SNAPANG but instead of entering 0, try selecting the end points of one of your horizontal lines.
Please feel free to attach your drawing here also If you want me to take a look.
