Since FreeHand gives you the option to scale down when you print, you
could, for example, design a large sheet, and print it at a reduced size to
get considerable accuracy. For example, FreeHand's basic units are 1/10,000
of a typographical point => 2834 units/mm (complain to typographers about
the 72 points/inch unit). You'd probably prefer dealing in millimeters, but
the underlying units are points, so there's a bit of roundoff when units
are displayed.
If you designed everything 10X larger, and printed at 10% scale, you could
increase the useable resolution.
Of course, you need to think about the resolution of the output typesetter,
which limits you to 10 micron dots on a 2540 dpi imagesetter (I don't know,
but suspect the accuracy of the imagesetter dot placement row-to-row is
probably less than IC lithography standard...)
