Flat CIF creates a CIF output without any hierarchy whatsoever. See the Program menu; the Flatcif module must be run before issuing the command. The command file sets up the CIF layer names and bloats; It is a pity, but not ChipNDale's problem, that reasonable designs will end up with millions of rectangles, more than most available CIF input packages can handle.

Flat CIF generates CIF output of the whole design, not only the selection.

Do check manually if the right CIF layer names and bloats are used.
