Summary0028500: Mesh - Artifact in shaded view of the shape
DescriptionDuring meshing with BRepMesh of the attached shape the algorithm reports OpenWire meshing status. This results in artifact displayed in shaded view in the form of a green line (see the picture).
Actually the faces for which the status OpenWire is reported are valid faces. It is needed to teach BRepMesh produce triangles for such faces, even if they are degenerated in a line, in order to produce conform mesh.

DC,

It would be easy to try to implement custom processing of cases consisting of two edges which ends are covered by vertex tolerances after integration of 0026106 as far it allows processing and modification of wires and particular edges.
