Impossible to find a consistent orientation except if the join operator manages to keep some edges as free sidesIn some cases you can get a result, if the Join operator has been able to keep superimposed edges as free edges (boundaries)Two possible orientations for surface 2, if the wrong one is kept, it will not be possible to add surface 3 to the join.

you must take into account the accuracy of the data to Join: if you choose a strict tolerance, the Join has many free sides and it takes time to correct themalso sometimes Join does not work with a strict tolerance (Join failure)On the other hand when you relax the tolerance, some gaps are hidden but the geometry still has gaps and may be unusable for later processingFor example gaps may cause visible marks on the manufactured partremember that a gap may be: finally Join removes all edges which are smaller than the merging distance, which can cause problems if the merging distance is too highThe suppression of small curves may later produce invalid faces (with self-intersecting edges)merging dist. = 0.001mm merging dist. = 0.01mm merging dist. = 0.1mm
