i am new to grasshopper and studying alone, i created a volume of closed curves from their controlpoints of many polylines(voronoi 3d structure) in space.and the polylines share the same edges. now i have a problem to isolate every single curve with its polyline and then creat a line between the midpoint on every edge of polyline and its closest point on the curve.if not isolate every single curve and its polyline, grasshopper would find the closest point on curves for one polyline. anyone could tell me how to resolve pls?
many thanks in advance,
yewei
