Height Exaggeration Ratio: is the value that the height is
multiplied by in the 3D view. The higher this value, the more
exaggeration, where 1.0 would result in no exaggeration.
; Hidden-line Removal : When checked, will hide
all the lines that occur behind other surfaces in the
3D View. The image shown here is identical to the
image shown on Page R-85 except the hidden lines
are not removed.
; Display the Difference : This applies only to DTM
stakeout. When checked, the vertical portion (z-axis)
of the 3D View screen is computed by the elevation
differences between the non-reference DTM surface
and the reference DTM surface. This will result in any objects that
occur above or below the reference DTM to clearly stand out as hills
and valleys and the volume information provided in the 3D View
screen will be between the staked points and the reference DTM.
When unchecked, the Datum field can be set to a reference elevation.
Cut and fill volumes in the 3D View screen will then be based on the
difference of a horizontal plane at the elevation specified here and the
non-reference DTM surface.
Datum: When the Display the Difference checkbox is unchecked, cut
and fill volumes will be computed in the 3D View screen based on the
difference of a horizontal plane at the elevation specified here and the
staked points.
View Direction (from view point to the center): allows you to
specify the exact horizontal and vertical angle in which to view the
DTM.
