Corridors Intersection

[rwatson654]

New to intersections/corridors  with C3D and would like advice. A portion of the project requires a 24" forcemain to be laid on existing ground surface.  The FM will have 24" cover for 12" either side of the pipe, then 3:1 slopes till daylighting to existing.  The FM crosses an existing road at the top of a berm. The road will be adjusted to cross the FM and 3:1 slopes daylighting to either the existing grade or the FM grades.  I can model the FM and Road separately with no problems but am not certain how to combine these two so the road surface daylights to both existing and the FM grades, removing the FM grades through the roadway.  Additionally there is new road that approaches the FM.  The new road needs to daylight to the existing surface and the FM grades.  Suggestions on how to proceed would be appreciated, see attached.

Create a surface for the FM grades if you haven't already.  Copy your existing surface and call the copy something like "existing with FM grades".  Select your new "existing with FM grades surface" and go to your edit commands.  Select paste, and paste your FM surface in.  Use your new "existing with FM grades" surface as the target for you're "new" road corridor.

Hope this helps.
