# need some help on a script for curves

Hi, i wrote a script that takes vetex from a mesh and makes lists of points which have the same coordinates in X and lists of points which have the same coordinates in Y. Lists are used then to make curves. finally, it is supposed to make a network of curves in Y and X which are “sticky” to the initial mesh. But the script takes too long. I haven’t found any infinite loop so i don’t know what’s wrong.:mad:
Is anybody can tell me how to fix it?
