Scanning major and minor symmetry features

Major and minor symmetry features can be revealed by Helium precise 3D model, like pictured here naturals, not proper facet junction pointing, and «twist» or shift of the upper and lower girdle facets.

It distinguishes Helium scanner from other scanner models.
