This command creates a .PRO file from user-specified offsets or
from specified descriptions on cross sections contained in a .SCT
file. The elevations of the profile are derived from the elevations
of the cross sections at the offset and the stationing for the
profile matches the stations of the cross sections. There is an
option to extend cross section elevations to reach the offset for
the profile when necessary. If, for example, a road design has "SH"
at some offset on each cross section, both left side and right
side, you can pull the profile from the "SH" descriptions by
specifying left or right side. So you can profile the shoulder, or
the "TIE" point to existing ground, etc. Alternately, if the
sections extend from offset 100 left to offset 100 right, you can
pull a profile at offset -30, or 30, in which case the program will
create a profile by interpolating the elevation from the sections
for each station in the cross section file.

[<Offset>/Desc]? press Enter
Enter the offset to profile (left offsets as negative)
<0.0>: press Enter
Extrapolate sections to this offset (<Yes>/No)?
press Enter This prompt appears if the program
detects that some or all sections do not extend to the requested
offset to profile.
If you chose Desc above, one of the advantages of the new file
loading dialog is that you can review the ASCII descriptions in the
section file, as shown below:
