So I see that we can weld a whole half of a symmetrical level and rotate it to make the other half. That would make it rotationally symmetrical. I saw someone ask if we would be able to use a mirror function that would give us maps with mirror symmetry with the same ease. The response was that they couldn't comment on features not already shown and I figure we may not get it. So I came up with this while brainstorming what you might do to make things faster. Tell me if I got something wrong.
