Quick newbie question: how do you know the reason why BooleanUnion “is not working” when two closed polysurfaces are clearly intersecting? I’m attaching a file where I would like that the small piece (top) unions the big one to have a flat surface at the top. I’ve always used BooleanUnion successfully but don’t know what can I do here?
Thank you in advance.
