I discovered the perfect protractor.

I drew a polar array in AutoCAD. 360 lines emanating from a common point.
Each line represents a degree. Believe me when I say it doesn't matter how
large the circle is, the lines are accurate. i.e equally spaced, even when
printed.. Every 5 lines is a solid line, the 3 in between hidden lines. At
22.5, 45, 67.5, 90, etc... are center lines. This helps you to see. the
center doesn't go to a messy blob. Terminate in a small circle, maybe a
dollar size. But alternate where you terminate each type of line i.e. the
center, the solids

It requires a little flip/flop during alignment, and guessing and erasing
with a pencil mark, but you can get it PERFECT. No other method/tool even
comes close. You can mark your angle/line/point anywhere within the size of
the printout. You can also cut a slit with a razor along one line, say 90
degrees, so you can put your pencil through it. Just adjust the starting
point, or make a calculation.

I printed some on my inkjet on mylar paper that I cut to 8-1/2" x 11', from
scraps from a printers shop roll, so my circle was a max of 8-1/2" side to
side, and 11" top to bottom. Just let it dry. If you go to a high-end
printers shop, the maximum side to side mylar is 36", but length is
infinite! And their $250, 000 OCE printers' ink is heat activated and
permanent

You can make many types of them, and print many, slice them up, cut them...
Mylar is see-through, almost indestructible plastic. printing is not
expensive if you need these. I don't know if you can buy it Office Depot.
You wouldn't believe how incredible this method is!

I'd love to hear back anytime if someone tries this and likes it. Believe
me, if you go through with it, you will be laughing at the discovery you
made.

You can take the drawing to the reproduction (copy)shop. They do literally
millions of .dwg files! CAD in a "copy" shop is a majority of the profit.
Astley -Gilbert Reproductions (Canada) for instance. I did this a while
ago. If anyone wants my file , I think I got it on floppy some where. Can
I put a .dwg or .dxf in a newsgroup?
