Profile Generation command draws a straight line from the point of exit
elevation to the point of re-entry elevation.
Sampling the Existing Ground from an ASCII File
Use the Sample From File command to sample an existing ground surface from
an ASCII text file. This command generates existing ground profile data from
the selected text file.
NOTE
You cannot execute this command multiple times to create multiple
surface definitions from multiple ASCII text files because every time the
command is run it overwrites any existing vertical alignment information.

followed by the elevation, separated by a space. The station cannot contain the
plus sign (+) character. The following lines are examples that the Sample From
File command can use:
