52846: It is impossible to select edge in OB as reversed edge for hypothesis

Browse Source 
52826: Radial Quadrangle algorithm meshes a quad face from which a circle was cut from but it must fail
52227: Group is not shown during edition
52780: Wrong mesh after STL re-import of a polygonal element
52825: Sew Borders does not care of segment adjacent to split faces, thus segments become non-conformal
52824: Sew Free Borders sews borders as conformal thus producing very skewed quads instead of polygons
