Tell me how to choose intersection lines?
(blue dotted line)
Hi - Region Intersection perhaps?
and if lines in one note and not in three?
Hi - you should always post your gh file with any Rhino geometry internalized so that people don’t have to guess what you are looking at…
why does rearrangement of rectangles sometimes work, then not work?
Here is a quickie Python scripted solution…
CoplanarOlaps.gh (3.1 KB)
Here is the non-GH scripted solution to run inside Rhino…
FindClosedCrvOlaps.py (1.5 KB)
Without any *.gh file, that’s still only guessing… probably because the order in the list matters a lot.
