This command is similar to the Route by Terrain, except that movement is now restricted to along the horizontal alignment definition.
The program requests the following input data:
·Segment: Segment file containing the road’s geometric definition, including at least the ground plan alignment and elevation drawing, the cross-section profiles and the cross-section template used.
·Surface: Optional file used to generate the terrain upon which the road will be drawn.
·Initial station: Point at which the tour starts.
·Final station: Point at which the tour ends.
·Observer Height: Height in meters above the road’s grade line.
·Alignment Displacement: Transversal offset on the alignment (negative to the left and positive to the right).
·Speed: automatic travel speed inside the viewer.
·Direction: Direction of movement along the road (Direct from initial station and Inverse from final station).
