(...) Hmmm, it seems to me that any algorithm that can find the missing Type 5 lines (in order to create the dummy entries) should be able to find *all* of the Type 5 lines. Some missing lines is just a special case of all missing. So just include (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

Secondly, the current algorithm is actually useful to part authors, since it can visually highlight missing conditional lines. (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

I realise this is largely off-topic to the oriinal thread but I've always been curious why the use of quads is encouraged when just about every other format and rendering engine sticks to triangles.

There is one more thing to add to Joshua extensive explanations: coplanar triangle pairs are not assembled into quads.
