Since LDView was used for the part images, and there are plenty of smooth
curves, it appears that stl2dat did a reasonably good job of putting in
conditional lines (linetype 5). There are some parts where they are
curiously missing (like the interior hole of 33286), but overall I’d say
these look really good.

I see in the stl2dat release notes for version 1.12 an options -o5 (which isn’t
in the documented options list above) that makes it generate convex optional
edges (I think it means concave). That’s probably why the inner part isn’t
smooth in 33286. (I’m guessing that -o5 wasn’t used during the conversions.)
I’m not sure how people feel about optional edges on concave regions. As far as
I know, LDView is the only program that actually makes use of that info, and in
all other programs it’s just useless. (Worse than useless, actually, since it
slows down any program.) Given the definition of linetype 5, having them could
be considered to be improper behavior. I’ve considered changing LDView’s
smoothing algorithm to smooth everything that’s less than a certain angle and
doesn’t have a type 2 line at the edge. (Or, more likely, making it optional.)
That’s a big task, though, and I’ve never gotten around to implementing it.

| That's great news. Just out of curiosity, do the green and blue bits have any significance, or are they just random?
