I am trying to assign unique ID numbers to catch basins. Ideally the numbers would be somewhat in sequence as one travels along the drain pipes from the outlet. IDEAL NOT IDEAL [A picture containing object Description automatically generated][A picture containing object, clock Description automatically generated] OUTLET OUTLET Can someone suggest a workflow, tool, or a python script that might help me accomplish my goal? I find the idea of doing this manually for thousands of catch basins abhorrent. I would welcome any suggestions.
