Distance only?&nbsp; What are the units of your data and what are your units of distance that you are solving for?</SPAN><BR /><BR /><SPAN>If you are only seeing it in a few cases, you might isolate those cases and see if you do in fact have connectivity along the route you think it should be taking.&nbsp; What I've done in cases like this is manually place stops along the route I like and see if it will solve along the way.</SPAN></BODY></HTML> Tue, 21 Jun 2011 15:58:53 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/network-analyst-closest-facility-tool/m-p/548727#M5335 JoeBorgione 2011-06-21T15:58:53Z
