Well, I did some tests walking the tree and printing out all line type 2 as cylinders,
but I didn't think it looked to well.
Mostly because at some edges you only see 1/4 of the cylinder,
and at other edges you see 3/4 of the cylinder.

L3P doesn't walk the tree (yet), but I could add an option to L3Lab
to export a "POV cylinder file" that you could include in the L3P POV file.
It could even have support for line type 5 since the camera location is
in the POV file...

(...) This is so very true, and troublesome. POV-Ray does not support the concept of a line in 3D space, so L3P cannot directly translate LDraw lines to POV-Ray entities. Lars, at one point we talked about the possibility of having L3P use cylinders (...) (22 years ago, 3-Apr-04, to lugnet.cad, lugnet.cad.dev, FTX)
