Hello everyone!

I was wondering how it would be possible to draw a continuous polyine along the vertices of a square collection.

I have a square collection that comes from two different structures:

Blue squares are contained in one tree with five branches, each containing one square,

Red squares are contained in one tree with five branches, each containing a different ammount of squares ranging from one to four.

The task I want to perform is to build a continuous polyline along each outer vertex of this collection of squares, like a border line. (more or less like the white line)

I tried this approach using the convex hull component but it builds a region that contains all the squares and avoids some vertices in the inner part of the square collection.

I will leave the file below, any help would be appreciated.

*(I’ve customized components so they look pink, everything is working fine)*

best regards,
