#35mm slides from Autocad

What is the best way to make 35mm slides from Autocad?

Thanks for the #.

I use Ektachrome 200 at f11 and 1/2 second in a dark room, bracketing each
shot. I use a 90 mm 1:1 macro lens and a Nanao t560i 17" monitor. The
main trick is to make sure that the monitor and camera are absolutely
square with each other. Last time I borrowed my dad's heavy duty Bogen
tripod. I have to get me one of those.
Barring that, I use a screen capture program and find someone with a good
Matrix or Lasergraphics camera.

Thanks for the photo tip.
At what resolution do you run Autocad?
I was looking for an Autocad driver for vector output to a film
recorder, preferably Lasergraphics, which I already have.
Does Autocad have postscript output? If it does then maybe
Freedom of Press would work.
How do you like the Nanao t560i?
David:
"Best" for what? You can shoot slides with some slow film and a tripod –
average quality, but cheap if you already have the equipment. You can send
out AutoCAD SLD or DWG files to a service bureau – should be good quality,
but expensive per-slide cost. If you're going to do a lot of them, buying
your own film recorder might be worth it – convenient and good quality, but
large up-front cost.

I see that you've already had some responses to your question. The answer
really depends on what kind of quality you're trying to achieve and how many
slides you're going to need. You can shoot them directly off the screen in a
completely dark room, but you're limited by your screen resolution and your
own photographic ability. And unless you use a sufficiently long lens,
you're going to get some screen curvature at the edges of the screen.
There are plenty of service bureaus out there that do 35mm slides from
computer files. But you'll need to check with them and see what file formats
they can handle. An HPGL or DXF file will yield a resolution independent
slide, meaning that the resolution of the slide will be based on the
capabilities of their film recorder, not on the resolution of your computer
screen. If you do a SLD or use a screen capture program, you'll end up with
a slide that may be imaged at 2000 lines, but will just be a high-res slide
of your 640×480 VGA screen. That's not necessarily bad, however. That's what
we print in CADalyst all the time and its fine for computer screen shots.
If you're going to make a lot of slides all the time, look into buying your
own film recorder. CADalyst reviewed three units in the September issue. Two
were quite reasonably priced as film recorders go ($4000-$4500). With your
own unit and some programs like HiJaak, you should be able to take anything
you have on your screen and output it as a 35mm slide. And they're all very
easy to use.
