NOTE
The values you enter against these prompts are not used in calculating the
subsurface volumes. The adjustment factors entered in the Design
Control
ä
Volume Adjustment Factors command are used exclusively. If no
data is entered for any or all of the surfaces, then an adjustment factor of 1
is applied.
8 Specify the range of stations.
The defaults for the beginning and ending stations are based on the beginning
and ending stations of the current alignment. Accept the default or enter a
different range of stations.
The command calculates the data and outputs it to the file. To view a table
listing the section codes used in the ASCII text file, see Outputting the Volume
Data for Surfaces to an ASCII File in this chapter. To view a sample output file,
see Volume Data for Subsurfaces  Sample Output File in this chapter.
Volume Data for Subsurfaces - Sample Output File
The following text shows the format for the ASCII text file:
Alignment name
report type,volume type,curve correction,adjustment factors,catch/ROW
surface,int sta,ext sta,area,centroid,adjustment
factor,volume,cumulative volume,radius,radius half way to next sta
The format for an ASCII text file consists of the following components:
n
The internal station is the original station value as the alignment was
defined, before station equations are used.
n
The external station is the current station value. If you havent used station
equations, these values will be the same.
The following is an example of the subsurface volume output in the ASCII text
file. Any line beginning with either a number character (#) or semicolon (;) is a
comment line.
