I stakeout all bridges, underpasses, overpasses, gutters, ditches etc the way the pictures below show.
This is possible following the below steps...
1. creating corridors using Civil 3D
2. using custom Microsoft VisualBasic.NET 2013 DLL program running from within Civil 3D (using NETload command) to export Corridor Sections (no need for sample lines) as proper LandXML cross sections
3. using custom Microsoft VisualBasic.NET 2013 EXE program to load Civil 3D LandXML exported alignment and profile, clean it from superelevations and cross sections that might have been exported also with it and finally attach the above exported LandXML sections to a compact LandXML file
4. using Leica LandXML converter from LandXML to RoadRunner job.
All overpasses, underpasses, bridges, boxes, walls i staked out, for the past three years, were made this way.
If anyone wants to try the above methods just leave a comment and i will create a new post with links for the mentioned programs and instructions.
