I have line segments (vertex only a beginning and end) and want to create polygons for each (including their attributes).

To visualize what I’m trying to create - here is a mock up of where I want the polygons split (red lines were drawn in by me and the green polygon is just a buffer of the dissolved line segments). The centerline represents the spans.

Red lines = where I want the polygons split

Doesn't sound too crazy but it’s kicking by butt at the moment. Any idea or suggestions?

I tried to solve this by generating cutting lines from the vertices at the end of the points using the NeighborFinder. Attached workspace.
