What? No, I'm not saying that. The highlighted area should be two parts, but it didn't slice through. The lines are there, but it's still two separate areas!!!

It doesn't matter if it's a solid or not. It still doesn't slice through.
I've attached a simplified example.
If I do intersect-with-model on the bump that hasn't been cut out (the same one in the picture), it won't split.
Edit: I noticed that after splitting, there was a single polygon where the outline formed along the surface of the main object that was not cut . When I drew a line cutting it (the polygon), the bump shape separated immediately in two. I don't know why Dave didn't experience this: [image: aVyB_nocut.png]
