Creating the Existing Ground Cross Section Data
from a Text File - ASCII File Format
The files used with the Sample From File command must be set up using the
following format:
station
S surface name
offset elevation
offset elevation
E
The lines beginning with S indicate the start of a new surface. The lines
containing an E indicate the end of a station/section.
The following example illustrates a sample file used by the Sample From File
command. This example creates cross sections with two existing ground surface
definitions, SF1 and SF2. The information in the left column is what you need
to include in your text file.
NOTE
The information in the right column is for explanatory purposes only. Do
not include these descriptions in your text file.

E end of station
The format of this file is very important:
n
Station values must be in ascending order.
n
Station values must be entered as decimal values. Do not enter stations in the
format 10+00.00.
n
Blank lines cannot exist at the beginning or end of the file. If there are blank
lines, then the Sample From File command reads them as the end of the
file.
n
Blank spaces cannot exist at the beginning or end of a line.
n
Blank leading headers cannot exist in the file.
n
The first item of the file must be the first station number.
n
The last item of the file must be an E, indicating the end of section.
