Re: arcs in 3d?

Hi Jeffrey,

Sorry for the problems; it's indeed a version issue (but probably not
worth installing the very latest minor version to get the needed
functionality:)

To get a working example file, please remove the "arrow_fill"s (they just
print black arrowheads), and replace the "dot" commands with a dot and
label command, as in:

  dot(posn, offset, "text", alignment);

becomes

  dot(posn);
  label(posn, offset, "text", alignment);

--Andy
