Summary0031453: simple chamfer smashes vertex tolerance
Descriptionchamfering a box causes the new vertices to have a much looser tolerance than expected. A simple blend in the same condition keeps Precision::Confusion.
Steps To Reproducepload MODELING
box b 20 20 20
explode b E
chamf c b b_1 1.0
maxtolerance c

## Tolerances on the shape c (nbFaces:7 nbEdges:15 nbVtx:10)

    Face : Min 1.00000e-07 Max 1.00000e-07
    Edge : Min 1.00000e-07 Max 1.00000e-07
    Vertex : Min 1.00000e-07 Max 1.00000e-04

I have not tested with an older version, but I believe this is a regression as I haven't noticed this behavior before.
