Haha I knew there was a reason I did that. :)

I can triangulate the mesh prior to export, however that fattens up the already
giant file, and can introduce undesirable smoothing artifacts. Generally, it is
considered "good form" to ensure there are no coplanar quads when you are
modeling something. Perhaps a rudimentary GUI with a triangulate/don't
triangulate option would work best?

Still trying to wrap my head around how to set up these lines, but in a fit of
frustration I did arrive at one interim solution for conditional lines. By
putting all the control points at 0,0,0 I not only make poor LDView pitch a fit,
but it smooths it nicely. :) However, after a quick test I realised I now have
a more ambitious goal - smoothing groups. I can duplicate them in LDView, it
just is gonna take a lot of headaches.
