This routine takes a full suite of road files (existing and final
profiles,
existing and final cross sections and the centerline) and presents
three
graphical
windows showing the road in plan view, profile view and section view,
with
a slide bar that let's you "drive" the road or project from start to
end.
In addition to applying to roads, the command applies to any set
of
existing and final sections that follow a horizontal alignment
(centerline),
such as for channels and embankments. As you move the slide bar
left
and right, your position is shown in profile view, in plan view and in
cross
section view. The cross section graphics can be scaled to fit the
allotted
screen space, or can be set to a scale such as 1H:1V or set to
exaggerated
scales (2H:1V up to 10H:1V).
The current station is displayed as you move the slide bar. You can zoom and pan the cross section view, and you can also enter a specific station to study. Stations that do not exist in the cross section files will be interpolated.
