ShortestPathFinder : Why doesn't it calculate the path for the 4 features?

Hi everyone!

I have some "from-to" path features (FROMTO.shp) that I need to use to calculate the shortest path across a network (NW.shp).
However, it doesn't seem to work for all 4 features (just one), does anyone know why?

I've attached the files for reference.

Thanks in advance!

Hi ​@gbcfgeo2025 Use a NetworkTopologyCalculator to test for unexpected gaps in your networks.  Then use a Snapper or AnchoredSnapper to fix those gaps.

Hi ​@gbcfgeo2025 ,

Network lines must be topologically connected. Not only Snapper/AnchoredSnapper but also TopologyBuilder might be necessary to construct networks.

Regarding From-To lines, note that every vertex of them should exactly match a node of network.

See also the Help for ShortestPathFinder to learn more.

 

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?
