Opposite edge list direction in pgon 1. error

"Opposite edge list direction in pgon 1." error
This 3d error popped up and I've been trying to chase it down
with no success so far.
I've done the obligatory isolation thing by dividing up the building alternating with
the thin and thick marquee and got it down to a small area,(or so I had thought) and it seems to
be a isolated in a small section of stacked stories, however when I use the thin marquee on
that area (with each individual story) I don't get the error, but with both stories
(thick marquee) error I do.
And in error area, there are not "objects", Just walls and slabs (or so it seems).
When I say to "continue" 3d generates full view as would expect.
I'm stumped.

Of course I can turn off the error reporting in the WE , but it would be nice like to know
what the heck might be going on.

Slabs sound like the likely culprit. Try them one by one.

Hi
Thanks for the reply.
I'll adjust the slab a bit and see if it goes away, and or comes back at some point.
Any idea of what the specifics of that message is trying to convey, other
than the obvious, of there being an error?
Seems like the convoluted verbiage is trying to tell me something.

I'm not exactly sure, but it sounds like one of your edges got messed up, making an impossible shape (although I thought this was usually a "polygon degenerated" error). Pick one slab at a time and go to 3D window (F4 - selected objects) until one gives you an error.
