Hi Olga - why does the "mirroring" aspect concern you? A mirrored reflection does not by itself indicate a lack of continuity, it is about the matching up of the shape and flow of reflection lines across the seam.

The view from the other angle that you show does seem to show a small lack of continuity.

However, you're also getting significant additional artifacts from using a coarse analysis mesh and not having the pieces joined together.

Make sure to join the pieces together and when doing the analysis adjust the analysis mesh density to be much higher than the default density. That will help you see more of the true surfaces rather than getting distracted by artifacts caused just by the coarse mesh itself.

Having surfaces that are unjoined next to one another makes them get meshed independently and the resulting analysis meshes do not share vertices at the common edge, which can lead to differences in the display especially when using a too coarse mesh, that's why you also want to join them together to get a better analysis.

Also, I'm not entirely sure which model you are analyzing here, is it the one that Dan posted above "1693_Swan6.3dm" , or a different one?
