The 3D View Settings screen is used to configure the information
displayed in the 3D View screen.

;

Height Exaggerated to the Maximum

: When checked,

the height exaggeration is automatically set to a high
value. When unchecked, the height exaggeration can be
set manually in the next field.

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-
69 except the hidden lines are not removed.

;

Display the Difference

: This applies only to DTM

stakeout. When checked, the elevations in the 3D View
screen will be distorted so the reference DTM will become a
flat surface. This will result in any staked point that occurs
above or below the reference DTM to stand out as hills and
valleys.

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.
