Hello Amedeo,

in a tunnel network regulation, so with reference points only outside, is it possible to introduce azimuthal observations determined along the polygonal development with a gyroscope?

The azimuthal observations are similar to direction angles (i.e. oriented directions). JAG3D supports non-oriented and oriented directions. Since azimuths are related to the north, you have to uncheck the additional parameter "Orientation o", see screenshot

(I will correcting the mistake in writing within the next release)
