I have a group of curves that are all touching. I am trying to select a subset of these curves, and extrude them by a distance that is based on an attribute of each of all the immediately adjacent (touching) curves.

I can select the subset no problem, and have successfully selected the adjacent curves. The problem is relating those adjacent curves to the specific subset curve that they’re touching.

e.g. if I have 3 subset curves:

{0} touched by {1} and {7}

{3} touched by {7}, {8} and {9}

{4} touched by {11}

Hopefully the attached definition helps articulate what I’m trying to do.

Blue curves are the adjacent lots. Red extrusions are the filtered lots. Light grey curves are all of the other geometry.
