Re: [Jmol-users] Screen position of an atom?

[James <ja...@ry...>]

Thanks Angel. I see that echo has almost everything. But, the reason I was
trying to use labels is because they can have a line to an atom. After
reviewing "draw ARROW" in the hopes that it could substitute for that line,
I don't see that it is possible to draw from a 2D point (e.g., top left) to
a 3D point (an atom). I tried assigning echo an ID and drawing from that to
an atom, but (as I suspected - just hoping I could trick it) since echo
isn't a draw object it doesn't work. I can't find a way to bridge that
2D/3D coordinate issue, which label does automatically.

Thanks,
James
