Is this rule generally needed if I want to topologically connect two line objects with different asset types via a node/junction?</P><P>I have carried out this test. The following two junction-edge rules can be found in the Electric Utility Network Foundation data model:</P><UL><LI>Electric Junction/High Voltage Attachment/AC Overhead HV &lt;-&gt; Electric Line/High Voltage Connector/AC Connector HV</LI><LI>Electric Junction/High Voltage Attachment/AC Overhead HV &lt;-&gt; Electric Line/High Voltage Overhead Conductor/AC Overhead HV</LI></UL><P>I have created an “Electric Junction/High Voltage Attachment/AC Overhead HV” and connected an “Electric Line/High Voltage Connector/AC Connector HV” from one side and an “Electric Line/High Voltage Overhead Conductor/AC Overhead HV” from the other side.</P><P>When I now execute a connected trace starting from any point on one of the two lines, all three objects end up in the result set. For me, this means that there is a topological connection between the line objects with different asset types. Do I still need an edge-junction-edge rule for this case and if so, why?</P><P>Many thanks for your help, best regards,<BR />Jürgen</P> Thu, 25 Apr 2024 09:47:39 GMT https://community.esri.com/t5/arcgis-utility-network-questions/when-exactly-do-i-need-an-edge-junction-edge/m-p/1415205#M3770 JürgenBiendara 2024-04-25T09:47:39Z https://community.esri.com/t5/arcgis-utility-network-questions/when-exactly-do-i-need-an-edge-junction-edge/m-p/1415208#M3771 <P>You only need and E-J-E if you do not want the Edge to end with a Junction.&nbsp; Also, for this rule to be enforced(create a Error Feature), you need to ensure you do not have an E-J rule for those AG/ATs.</P><P>Lets use a pipe example.&nbsp; I want a Pipe to connect to a Pipe through a Union.&nbsp; I never want a Pipe to end at a Union(if so, water would be flowing into the ground).&nbsp; So I could use a Pipe To Pipe Via Union.&nbsp;&nbsp;</P> Thu, 25 Apr 2024 09:53:59 GMT https://community.esri.com/t5/arcgis-utility-network-questions/when-exactly-do-i-need-an-edge-junction-edge/m-p/1415208#M3771 MikeMillerGIS 2024-04-25T09:53:59Z
