Summary

0028911: BRepAlgoAPI_Cut invalid result

Description

Applying cut to two valid shapes produces an invalid shape as a result. The result even cannot be fixed automatically using ShapeFix_Shape.

Steps To Reproduce

Draw[31]> restore s1.brep s1
s1
Draw[32]> checkshape s1
This shape seems to be valid
Draw[33]> bopcheck s1
This shape seems to be OK.

Draw[34]> restore s2.brep s2
s2
Draw[35]> checkshape s2
This shape seems to be valid
Draw[36]> bopcheck s2
This shape seems to be OK.

Draw[37]> bopargcheck s1 s2 -C #F
Shape(s) seem(s) to be valid for BOP.

Draw[38]> bop s1 s2
Draw[39]> bopcut res
Draw[40]> checkshape res
On Shape faulty_1 :
BRepCheck_BadOrientationOfSubshape

Faulty shapes in variables faulty_1 to faulty_1

Draw[41]> fixshape fxd res
Draw[42]> checkshape fxd
On Shape faulty_1 :
BRepCheck_BadOrientationOfSubshape

Faulty shapes in variables faulty_1 to faulty_1
