i have 2 shapes:
1) the object i want to cut (a shape composed by ~40000 surfaces)
2) an halfspace (build by a shell created from a wire)
Using BRepAlgoAPI_Cut i can cut it, but if i change the reference point of the halfspace (to change the side of the matter) i always get the same result.. But i think i should get the "other" side of the orginal shape.
The shell that describe the halfspace starts and ends outside the bounding box of the shape i want to cut.
