Hi Travis,

I think your "semi-flat" category is a sub-set of my "smooth" category...the key here is that it looks flat until you look at the neighbors, right?

My smooth category basically means "participates in smoothing after flattening". To this end, it's not really necessary for a program to pre-smooth the part; the part is going into the smoothing process later with neighbors considered, and the smoothing algorithms I've seen tossed around don't benefit from pre-smoothing some vertices.

So while semi-flat may be semantically different (e.g. "participates in smoothing after flattening, but flat on its own") I'm not sure it's a huge win to define it. There's certainly no harm in defining it if we want to be more specific.

But I definitely agree that rect3 is _not_ a candidate for "FLAT" tagging even though it is, ironically, flat. Because it is missing an edge line we must be pessimistic and assume that another part will join, of which case 33243.dat is a perfect example.

By comparison, rect.dat could be tagged flat. Because the quad is bounded on four sides by solid lines, we can safely assume that it was meant to be flat shaded.

Cheers
Ben
