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.

Profile of offset or template description [<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:
