Incomplete boundary curve

[Alvin_Tseng]

Hi all, I am trying to get the intersecting region of this pattern.
Not sure what else I need to do to get this right. It’s not reading all the intersecting lines.
Thanks for the help guys!

Region Intersection component works for the closed curves.You can use Trim with Region.
