[Therion] Switch off measured cave passages

[thomasschilter at bluewin.ch]

Dear
Therion Community
Our caving
club is working on processing our old survey data. We are trying to display our
data with the help of Therion and the Loch programme.
Among the
caves, the Hölloch is represented with over 200 km of passages. The survey data
has been added over 70 years. This results in a problem that already surveyed
passages were re-surveyed years later. In addition, a surveying network was
drawn through the entire cave and recorded with theodolites to increase
accuracy.
In order to
represent all the passages, there are therefore overlaps; some passages are
drawn twice in the Loch programme. However, all these surveys are needed to
calculate the cave.
My question
is, is there a flag that makes it possible to switch off or hide measuring
sections in the LRUD data without these being excluded in the calculation? Or
what other solutions are there?
 
Thank you
for your answers.
 
Kind
regards
Thomas
