Lines are incorrect, but I imagine it will be a simple fix in the rules file.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="AdamChestowski_0-1691658698973.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/77766iEB15928E53938FC4/image-size/medium?v=v2&amp;px=400" role="button" title="AdamChestowski_0-1691658698973.png" alt="AdamChestowski_0-1691658698973.png" /></span></P><P>I encountered also a similar problem on freeway exits, but it was sufficient to change the nodes "Smart" option into "Junction" or "Freeway" and work from there.</P> Thu, 10 Aug 2023 09:18:03 GMT https://community.esri.com/t5/arcgis-cityengine-questions/creating-merging-lane/m-p/1317288#M11106 AdamChełstowski 2023-08-10T09:18:03Z
