Andrew Chuck asks:

Q: Cave 1 is attached to the defined connection point and cave 2 is not?

A: Both caves need a reference points at the entry (missed in cave 2) and switched on adjustment (Calculate-Adjustment-Auto, missed in cave 2).

Q: How were the coordinates of the "Link" point calculated? Were they calculated as the alignment of the measurement sequences from both caves?

A: The position of the link point is set manually (somewhere between the two unclosed end points). For our surveys we choose the end point of the cave with better accuracy.
