Just to clarify, the above isn't quite accurate (on two points). First of all,
LDView 4.0.1 (the latest release) doesn't support this at all. Secondly, LDView
4.1 (which is forthcoming, but hasn't had even a beta release yet) will have
support for 3DS export, but not Wavefront OBJ export.
I sent Michael a development test build, and I also sent him a program that
converts from 3DS to OBJ on the command line (which isn't and won't be part of
LDView). Additionally, as far as I can tell LDView's 3DS output is likely to
only work in certain programs. As far as I can tell, it is impossible to
produce a 3DS file that all 3DS-aware programs will accept from any LDraw part
that isn't BFC certified. Additionally, I haven't yet implemented BFC support
in the 3DS export, so many programs just don't like the files I'm generating.

| (...) Yep. I created a minifig and imported the 3DS file into MeshLab. The improper BFC is very apparent. (You can see how part authors simply created one half of a part and then mirrored the primitives to create the other half.) -Mike (15 years ago, 14-Apr-09, to lugnet.cad.dev)
