Hi,

apparently the --gen3D option takes ages and does not work for
mixtures in most cases.
Does anyone know the reason and/or a workaround?

An Example:
obabel -:"CNC[C@@H](c1ccc(c(c1)O)O)O" -d --gen3d -osdf
works fine and takes about 8 seconds on my machine.

obabel -:"CNC[C@@H](c1ccc(c(c1)O)O)O" -d --gen3d -osdf
takes about 5 minutes, and produces an erroneous 3d-structure (see
below, one bond length is >3).

Kind regards,
Martin
