Summary0027997: Boolean section of two solids results in a broken section
DescriptionIn OCCT 6.9.1, when the appended two solids are intersected using the bopsection command, the resulting edges do not form a closed contour. Probably, that is the reason why the common operation fails.
checkshape, bopcheck and bopargcheck say that the solids are OK.

In OCCT 6.9.1, the result of the intersection was better.
