Summary0029431: "checkshape" for a single face depends on the orientation of the face
Description"checkshape" command does not reports invalidity for the attached face. Changing orientation of the face to Forward, allows "checkshape" recognizing the face as invalid.
Such behavior is explained by the fact that BRepTools_WireExplorer (used in BRepCheck_Analyzer) depends on face's orientation. For a Reversed face it returns 6 edges, but for a Forward face it returns only 4.

The problem has been detected in the test case "chamfer dist_angle_sequence B5".
Steps To Reproduce# test chamfer dist_angle_sequence B5 1
# explode result f; copy result_1 f

binrestore [locate_data_file bug29431_f.bin] f
don f
whatis f
# FACE REVERSED
checkshape f
# OK
explode f
expwire f_1 f
# BRepTools_WireExplorer donne 6 Edges


orientation f F
whatis f
# FACE FORWARD
checkshape f
# faulty
explode f
expwire f_1 f
# BRepTools_WireExplorer donne 4 Edges
