The issue I'm having is when I LANDXMLIN the surface to my working CAD file it also imports all the 3D polylines with it. Is there a way to import just the surface and not the 3D polyline?</P> Mon, 22 Sep 2025 21:22:27 GMT https://forums.autodesk.com/t5/civil-3d-forum/surface-export-import/m-p/13821248#M260574 Sab101425 2025-09-22T21:22:27Z https://forums.autodesk.com/t5/civil-3d-forum/surface-export-import/m-p/13821258#M260575 <P>Better IMO to data shortcut the surface then bring that in your new drawing. Once you have it in you can promote it which creates a snapshot of your surface. Then, you can edit it anyway you want after that</P> Mon, 22 Sep 2025 21:35:14 GMT https://forums.autodesk.com/t5/civil-3d-forum/surface-export-import/m-p/13821258#M260575 RobertEVs 2025-09-22T21:35:14Z https://forums.autodesk.com/t5/civil-3d-forum/surface-export-import/m-p/13821270#M260578 <P>That worked.
