I want to know how to proceed in order to identify the Side limits number of closed polylines ( 0,1, 2,or 3 ) that overlook the outside ( the patio is considered outside: the black rectangle in the folder)
All the polylines are rectangles or squares and they are arranged in checkerboard (orthogonal and parallel)
I tried Curve proximity but it doesn’t work any idea please.
If I understand your description correctly, then this might be helpful to you…
Not sure, but I was reading the question more as something like this:
