We have been members of OpenDWG then Open Design Alliance for years. Teigha
is not open source, but we never paid any fee to use the converter/viewer,
I don't know if there is any limitation to use the (binary) libraries
included. I don't think so, but I may be wrong.
Licensing the source is unfortunately not free (as in free beer) and open
is "members only" which is a real pity.
Anyway, GDAL has a new driver based on the free (as in free speech as well
as in free beer) Libopencad (https://github.com/sandyre/libopencad), it's
called OpenCAD: http://www.gdal.org/drv_cad.html.
Unfortunately it does not cover DGN v8. I think Alexandr Borzykh could
extend his library to cover it as it is similar to DWG (it has no relation
to previous "true" DGN format).
