|Product Version||[OCCT] 6.5.3|
|Target Version||Fixed in Version|
|Summary||0023378: BRepAlgoAPI_Cut returns wrong result|
|Description||The following cut operation returns a wrong result in OCCT 6.5.3: only one face is returned. |
In OCCT 6.5.2 the correct number of faces (2) are returned, but the bigger face is topologically not what is expected. It also cannot be displayed in shaded mode.

bop b_1 b_2
The object is cut by a cylinder. Both have only a very small volume in common. So the biggest part of the object should be returned (see Capture.PNG).
In OCCT 6.5.2 a very small face and a big face (which seems to be invalid) are returned.
In 6.5.3 only a very small face is returned, but the bigger face is not returned at all.
The problem has been discussed on the forum: http://www.opencascade.org/org/forum/thread_23599/?forum=3 [^] and confirmed to be reproducible.
