I have 3 parallel cylinders (axis parallel to y-axis), which I want to
intersect. Separately or merged they appear closed, but in the intersection they
appear open; only walls show. Is this a bug, and how can I fix this?

OK, I found it. My cylinders' tops were at the same height, and then the
intersection of the tops is empty. Solved by making them taller and intersect by
a
plane { y, 0 }

I've done that more times than I care too.
Have Fun!

My favorite way to screw up is making intersection of 3 or more things
at once, and then thinking why the heck I see empty picture. Surely,
when I finally replace it with a set of union - subtract - etc, I see
what I want and realize that yes, all these thing taken together at once
have empty intersection.
