Hello,

It looks like JAG3D does not understand the global adjustment with 2 stations.

Well, as shown by the screenshot at the github project website, that is not correct.

Is it a problem of our configuration / use of JAG3D? (we have tried to insert the stations like datum point but we get an error message).

Maybe, it is a problem with your configuration. However, without having your data, it is hard to figured out what is going wrong. I believe, it is a problem of your data handling. If possible, provide your data via Dropbox or any other service like that.

Please note: You have to separate each set of directions in it's own group. So, if you put all directions together in a single group - which means all directions share the same information about the unknown orientation - the adjustment will usually fail.

Is it a limit of JAG3D adjustment ?

No, I dont't think so - see the screenshot at github.

kind regards
Micha
