Summary0032187: Modeling Algorithms - Fillet isn't extrapolated correctly near vertex
DescriptionIn some situation of filleting non planar faces there are extremely high curvature extrapolation near edge's limit vertex (or blend command failing).
Also "test blend complex A3" failed in branch CR23731_7 failed because of this problem.
Steps To Reproducepload MODELING VISUALIZATION
restore [locate_data_file CCH_indushep.rle] s
explode s e

# the problem becomes visible, see sceenshots
blend result s 0.0034 s_8

# blend command failing
#blend result s 0.0035 s_8

# extremely high curvature
#blend result s 0.005 s_8
