If you have 3D locations that you want to use as Stops, put them in a point feature class and then use the GP tool CalculateLocations on it. Now you can Load Locations these 3d point features using the pre-computed Network Locations (not geometry) into a Stop layer and solve.</SPAN><BR /><SPAN> </SPAN><BR /><SPAN>Jay Sandhu</SPAN></BODY></HTML> Tue, 26 Jul 2011 16:31:43 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/3d-network-analysis/m-p/316204#M3052 JaySandhu 2011-07-26T16:31:43Z Re: 3D network analysis https://community.esri.com/t5/arcgis-network-analyst-questions/3d-network-analysis/m-p/316205#M3053 <HTML><HEAD></HEAD><BODY><SPAN>Jay:</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thanks very much for your help. I have succeeded on calculating the point feature, and I used it to create a Stop layer. If it is a right step, do I need to write a new model for network analysis just like tutorial do?</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thanks again.</SPAN><BR /><BR /><SPAN>Norsen</SPAN></BODY></HTML> Wed, 27 Jul 2011 03:04:00 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/3d-network-analysis/m-p/316205#M3053 NorsenRuan 2011-07-27T03:04:00Z Re: 3D network analysis https://community.esri.com/t5/arcgis-network-analyst-questions/3d-network-analysis/m-p/316206#M3054 <HTML><HEAD></HEAD><BODY><SPAN>Glad it worked. </SPAN><BR /><SPAN> </SPAN><BR /><SPAN>The model in the 3D network tutorial is meant for use in ArcScene where you can visualize the 3d lines but cannot directly add a network dataset and solve on it.</SPAN><BR /><SPAN> </SPAN><BR /><SPAN>Jay Sandhu</SPAN></BODY></HTML> Thu, 28 Jul 2011 17:09:05 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/3d-network-analysis/m-p/316206#M3054 JaySandhu 2011-07-28T17:09:05Z
