   On a side note, I’ve added code to LDView that will disable BFC support in any file that contains bow-tie quads (as well as generating an error). So it’s not like the problem can’t be worked around, but it does go against the official review guidelines. (Yes, I could have made it so only those particular quads didn’t get BFC’d, but that would have been a lot more work, and I didn’t feel it was worth it.) So the the first official LDView with BFC support won’t be hampered too much by this problem.

It’s funny how quickly I can forget the details of a complex task. For instance, I totally forgot about the NOCLIP BFC command (which can disable clipping for specific sub-sections of a file). Mind you, I implemented it, and believe that it works correctly, but I forgot that it existed when dealing with the above problem.

So I went back and changed my fix to use the functionality already present to deal with the NOCLIP command, and now only the “bad” quads have BFC turned off. Oh, and this change was cleaner and required less code changes than the old one. Gotta like that.

(Note that I'm sending followups to the lugnet.cad.dev.org.ldraw newsgroup alone, because that seems to be the appropriate group, but I think the audience of the lugnet.cad.dat.parts group should see this.)
