Does AutoCAD Map 3D, Civil 3D support GEOID files for displaying orthometric heights? Or must specialized survey software be strictly used in order to do so? i.e. MicroSurvey CAD, inCAD, Carlson Survey, Trimble Business Center, Traverse PC, etc? (forgot about QGIS)
Seems in order to properly design from the start using coordinate systems and orthometric heights, the software would need to be able to support BOTH, not just horizontal?
