Finding neighbor surface / curve

[jmjm]

guess i already found the solution on this one ^^

Grouping curves with coincident vertices

@HS_Kim, your code often seems to work well with his “city curves”, though not always? [coincident_edges_HS_Kim_2022Oct5c] coincident_edges_HS_Kim_2022Oct5c.gh (438.8 KB) P.S. Maybe if all of his curves were scaled up “slightly” (whatever that means?) from their center points so they are more likely to overlap/collide? Dicey…
