I'd like to see what the Revit Road and Terrain Extension is all about- but need, apparently, a LandXML file that will actually import properly. Does anyone have one they can create or share? Apparently, it's a file type that can be exported from Civil3D or created in other civil applications. When I've tried to import the few I've found on the web, I get an error that some of the segments are not attached or defined properly and it bombs out.
As an aside, I think that Revit REALLY needs some major development in the Civil arena- we really need to be able to do smooth pavement/surfaces and basic things like sidewalks, gutters, curbs, roadways more easily than we currently do. These things, really, are just as much a part of the REAL BIM as are walls, floors, roofs, etc...
