JOIN command does not join lines

[Alas_1234]

I have tried to create polygon from many polyline as can be seen in the topic:

https://forums.autodesk.com/t5/autocad-forum/how-to-convert-polyline-to-polygone/m-p/11946722#M11052...

I  fixed things like overlaps and self-intersections points and decreased all to only two polylines. But they couldn't join to each other.

I would happy to hear any advice about this issue. Thanks.
