As far as I know, there is the "Grow Streets" option under "Graph", yet it doesn't allow me to introduce my own streets, extent polygon or other layers to be excluded (i.e. lakes, buildings, parks).</P><P>Any suggestions for a solution?</P><P>Cheers,</P><P>Mel</P> Tue, 07 Feb 2023 11:42:05 GMT https://community.esri.com/t5/arcgis-cityengine-questions/generating-random-road-network-on-existing-data/m-p/1255646#M10868 MelanieVT 2023-02-07T11:42:05Z https://community.esri.com/t5/arcgis-cityengine-questions/generating-random-road-network-on-existing-data/m-p/1255651#M10869 <P>Hi<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/656384">@MelanieVT</a>,</P><P>Have you tried using grow streets together with an obstacle map?
