Hello
It would appear that sd works within the centreline/endcentreline part
but not as part of a survey, however would it not be better if this
worked within the survey context.
Eg I have a few sump surveys with some dry surveys, all the sumps are
grouped into a single higher level survey for convenience
survey sumps
<===== It would be good to put the sd in here, rather than having to
specify it in
<===== every file, which is tedious when I decide to change it
include sump1.th
include sump1a.th
include sump2.th
....
include sumpn.th
equate # #
etc
endsurvey
This would be also useful when areas of the cave have been surveyed to a
lower grade.
just a thought
