Good afternoon or morning
I have a situation that I suspect might stem from user error, because it
affects only one project, the data is a little messy, and there are 30 m
miscloses involved, although Therion is good at dealing with such things, so
maybe that is not significant.
My other suspect is the kml model generation code, because that is
apparently the only thing that falls over. This has been, for this project
only, a problem for many years, and through many versions of Therion,
although it is likely that there was an old version that compiled it OK. I
have tried it on yesterday's version 3e14a09 and the behaviour is the same.
It is a large project involving many caves, some groups of caves, and then a
master cave at three different folder levels. I've tracked the issue down
to one cave, and if it is removed (and the station equates joining the other
centrelines are broken [of course]) the problem goes away. The export model
kml at all folder levels involving this cave will cause an untrapped error
if it is present with other caves. The problem cave will however produce a
perfect kml model if it is compiled stand alone.
It is notable that the problem only ever manifests with export model kml. I
can produce lists, loch and 3d models. Every type of export map plan and
elevation pdf and kml output is also fine.
If loop-closure survex is set, I get a truncated XTherion transcript and a
therion.log that truncates midstream.
If loop-closure therion is set, I get no XTherion transcript, and a zero
length therion.log file.
Similar to the log files, the kml files appear to be truncated midstream,
one or two hundred lines in.
I have checked the coordinates at the point where the kml truncates, so that
I could focus on that particular survey and leg. There is nothing untoward
there, however I suspect that the cause of the crash is not necessarily
right at the last station written. The log and kml truncations are fairly
consistent however, but not always the same if I make adjustments to the
input data.
Any insights out there?
Anyone else had similar behaviour?
I have copied some short extracts below.
