I have two polysurfaces, which I am trying to join via a boolean union.
Right now, the two polysurfaces are not overlapping so my understanding is that a boolean union isn’t possible. As proof of this, when I nudge the inside polysurfaces a few mm over, a boolean union is possible.
However, when I do a scale2D of the inside polysurface (so that it overlaps with the outer polysurface), the boolean union fails. That makes no sense to me, because it almost certainly is overlapping at that point.
Can anyone help explain what I’m doing wrong here?
