Hi, Brian,

I'm working with Norm on his panel project. I'll contact you off-line,
and send you a photo of the panel, with measurements. I'll use my
Panasonic TZ3, which has a 28-280 mm lens (35 mm equivalent figures).
I really appreciate your help; I'm a neophyte with AutoCAD.

You're lucky: the TZ3 has a very low "barrel" distortion. Avoid 28mm
and you'll be fine. See
http://www.dpreview.com/reviews/PanasonicTZ3/page3.asp
Make sure the sensor/lens is accurately placed in front of the
geometrical center of the panel, and that it's pointed precisely to
it, otherwise you'll have huge perspective distortion.

Hi, Brian,

I sent an e-mail to your gmail account with the panel photos and
measurements on 17 Feb. Did you receive it?

John, I never look at that account, I didn't realize it had
automatically been made my contact email. I'll fix that. Anyway, I am
just finishing it now.

Hi Guys
Does anyone have a 20B panel outline file that will work in Auto CAD
program. The 20B has a completely rounded top a flat bottom and steps
on both sides. *It is different than a 19, 20A, and is the same as a
20C.
Thanks Norm

I would also be interested if anyone has a .dxf *or *.pdf

There is a crude hack I've used from time to time, take a photo from
about 10 feet away and import that into autocad as an image file, then
scale to the correct dimension. I would want to check it against the
original before sending out to the water jet or laser people but it
can be useful. Send me the photo and accurate measurements at critical
points and I'll scale it for you.

Brian,

Do you use the panel image as a template and "trace" over it with
splines?
Didn't know a raster image could be used to program a cutting tool!

Have to trace it, yes. I have no idea what the file would do to a
water jet and I don't want to find out.

If you haven't found a shop to fabricate the panels, take a look at
this website www.emachineshop.com. You download their version of
autocad, draw your part, select materials, click, click, pay,
delivery. Three guys here ordered panels to spread out the set-up
cost and I recall it was about $120/each for 3mm aluminum nicely laser
cut. They also have water jet and every other process. I have no
affiliation with this company, just think it's a cool option for
projects.
