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.
