Bug: after the 'cut' operation, we have a valid shape (checked using checkshape). But if you look through the viewer, the shape looks not valid.
Possible causes: incorrect rendering, incorrect validation, incorrect boolean operation.

Note: the input is valid.
Note: please, after finding out the reason, change the category of the task.

Also note, that the
vaspects res -setBackFaceColor RED
command does not tint the faces. If this should not be so, then please create a separate task.
