Hello,

Ok I understand thank you.
How can I indicate to Jag that some points are free stations? I tried to put them into the "new points" group without coordinates (0 0 0 instead) thinking that it won't influence calculation but it seems that I was wrong, so I approximate these coordinates and now it works but really badly.

Here is my project if you want to check : https://www.dropbox.com/s/jmain19nc1r6kzu/omran_2.zip?dl=0

Kind regards,
Omran
