This command extends the offsets to the left and right limits for each station in a section file. The left and right offset limits are defined in the section alignment (.MXS) file. The elevations for the extended offsets can be extrapolated from the last slope from the existing offsets or the elevations can be carried flat from the last offset elevation. For example, consider section station with a left most offset of -192.5 and a right most offset of 197.3. If the MXS file had offset limits of 200 for left and right, then this routine would assign offsets with elevations at offsets -200 and 200. The resulting section file can be saved to a separate section (.SCT) file or overwrite the original SCT file.
