But the pipes are now way to big for that manhole structure. I want to make the bottom structure of the manhole bigger. en-USTelligent Community 12https://communities.bentley.com/thread/699765?ContentTypeID=1Fri, 04 Mar 2022 13:50:30 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e4d3e20a-2fea-41f7-bc82-01531d914925Karl Dauber<p>The Utility Properties will change the node properties in the &quot;analytical model&quot; where the hydraulic calculations are done, but these changes will not flow over to the Properties, which represent the &quot;physical model&quot; shown in the OpenRoads 3D model view.&nbsp; To change the physical properties in the 3D model you will need to select a different Feature Definition to change the node.&nbsp; If a Feature Definition for your desired node size is not available, then you will need edits to your WorkSpace to add the new nodes, including additional cells in the cell library, among other additions to the WorkSpace settings.</p><div style="clear:both;"></div>
