Are you looking for the downstream order of your lines? You mention a python script.

Yes, I am looking for the downstream order of my lines. I need the order ("index") as attribute value of the line. It could be solved as python script, but I would be glad for any other solution.

Thank you. </P></BODY></HTML> Tue, 16 Jun 2015 08:40:33 GMT https://community.esri.com/t5/python-questions/order-of-polylines-after-intersection/m-p/721016#M55817 DusanADAM 2015-06-16T08:40:33Z Re: Order of polylines after intersection https://community.esri.com/t5/python-questions/order-of-polylines-after-intersection/m-p/721017#M55818 <HTML><HEAD></HEAD><BODY><P>You might try using the Sort tool, perhaps with a spatial sort method. You could then use the FID field, which would be ordered in the new dataset, or add and calculate a field of your own.</P></BODY></HTML> Tue, 16 Jun 2015 15:42:44 GMT https://community.esri.com/t5/python-questions/order-of-polylines-after-intersection/m-p/721017#M55818 SepheFox 2015-06-16T15:42:44Z Re: Order of polylines after intersection https://community.esri.com/t5/python-questions/order-of-polylines-after-intersection/m-p/721018#M55819 <HTML><HEAD></HEAD><BODY><P>You might want to look into a geometric network it has a upstream, downstream trace options.
