If you get the depths out-of-order on the subsurface portion of the data entry screen you can have LOGDRAFT sort them -- note that, in most cases, this isn't critical, as the program can will work correctly even with out-of-order data.
To sort a source's subsurface section by depth:
- Open the source folder to be sorted.
- Choose Source > Sort by Depth.
The sorting order is determined by the data entry form used by the source folder: if you can't find the Sort by Depth menu, edit your data entry form's Form Settings to change the For sorting purposes... field to be Depth (see the directions given in this section).
