Thanks Bruce.
I have commented all the splays "extend ignore", and Therion is doing
now a good job, ignoring the appropriate leg (extend ignore 83 92). All
the splays "extend ignore" was confusing the Therion compiler.
This data is an export from Topodroid, that incorporates the "extend
ignore" command before the splays shots. I will comment to Marco Corvi
on the problem.
Bruce, I had already read your excellent wiki about Extended Elevation
and the Marco Corvi’s altervista web pages on extended elevations in
relation to loops
<http://marcocorvi.altervista.org/caving/tbe/m_04/m_044.htm>, but I had
not managed to solve the problem.
Best regards,
Evaristo.

An interesting situation. I have not tried to compile your data, but
notice you have extend ignore prior to each set of splays.
I don’t think extend ignore has any useful function with respect to
splays (but I am not sure).
I suspect what you have done is effectively follow ‘extend ignore’
with ‘extend left’ without any non-splay legs in between. Possibly a
confusing situation for Therion. Have a look at my understanding here
<https://therion.speleo.sk/wiki/extend#summary_of_all_extend_options_for_survey_centrelines>
(although it does not yet consider splays at all, or inverse
(backsight) legs properly).
What happens if you remove all the extend ignores prior to the splay legs?

*Subject:* [Therion] Conflict between "extend ignore" command and
inverse legs
Hi,
I usually do my surveys doing inverse measures. I go ahead by
positioning the points, and doing the measurements with the distoX2
looking back (inverse) and finally do the splay measurements at that
destination point. My assistant is in origin point, and don't have
survey experience, is only putting the target in the anterior point .
With this I get all the data (leg and from and to splays) to be able
to draw the sketches.
You can look a example the data results:

In this data I have a loop. The main passage is: 82-83-84-85-86-87-93.
And the secondary passage is: 87-88-89-90-91-92-83.
When I compile the data and produce a XVI file, Therion is making the
secondary passage the main centerline, breaking the main passage leg
"87 93".
I have tried to break the secondary passage with "extend ignore"
commands and is unsuccessful. I also tried to rename the connection
station and make "equate" sentence, and also is unsuccessful. I have
also interchanged the from and to station order.
I thinks is a problem with the inverse legs data and the "extend
ignore" command.
To avoid the problem I rename the leg "83 92" to "83B 92" breaking the
loop at the secondary passage. To export the plan I put and "equate 83
83B", and to export the extended profile I comment this sentence. It
works but it is a bit cumbersome.
Someone has had similar problems with the "extend ignore" commands and
has found some solution for its correct use?

Evaristo
