Spectra Precision Survey Pro v5.0 - Manual (Page 60)

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 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.
