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? Best regards, Evaristo
