In Illustrator you can set a work area of up to 5.77 metres x 5.77 metres and,
depending on chosen magnification, your 17" screen will show all or any part
either full size or magnified up to 6400% for fine detail work.
As for turning it into resistant material, try one of the following:
>
Save to ZIPdrive or CD, take to your nearest graphic arts/pre-press agency and
ask for a positive or negative 'emulsion down' on process film for
photo-etching or a paper print in up to AO size to be laid on a wooden/MDF
workpiece. For small photoetching up to about A3 this is a 'pie-dish' process
at home after which sizes I use a local specialist company. The dial plate
with curved roman numerals I mentioned is supposed to be ready tomorrow in time
to have the dial together for the BSS Conference next week.
OR
Save as '1 bit Macintosh' or '1 bit IBM/PC' and take it to your nearest sign
maker equipped with a CNC panel engraver. He will engrave in brass, bronze or
MDF up to 8ft x 8ft with an accuracy of 0.02mm anywhere on the panel.
OR
take the same file to any company equipped for water jet cutting if you would
like the design cut out like a jigsaw puzzle in material up to 8" thick. Wear
ear protectors if you want to watch the operation! Water at 60 000psi with a
pinch of abrasive added passes through a 1mm dia. hole in a diamond and cuts
with a burr-free edge and virtually no 'spread' in metal or stone.
I know little or nothing of stone working but I've read of photo/sandblast
materials which might not be durable enough to to give a full depth cut but
may last to give marking out for hand work thereafter.
I understand stone is now laser engraved with great success so I would guess
the same file mentioned above would work in a laser engraving setup??
Hope this is helpful Richard.
Best Wishes
