Description
Nearest ver-
tical tan-
gent point
Distance to the nearest vertical tangent point of the design.
Centreline
grade
Grade of the centreline at the current position.
Height dif-
ference at
3D chainage
Offset perpendicular to the vertical component of the selec-
ted line.
This value can be useful when dealing with pipelines, cables
and in the construction segment.
3D chainage
Chainage of the measured point is projected perpendicular to
the vertical component of the selected line.
