[Therion] Conflict between "extend ignore" command and inverse legs

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?

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.

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?

Best regards,

Evaristo
