Tracking the Elusive Tracing Paper

I've been doing a lot of reverse engineering using Deltacad. I scan a
1963-vintage mylar drawing and then paste it full size into Deltacad,
then I can trace directly over the image. I've done drawings 13 feet
long and 5 feet wide that way (these are Sikorsky S-64 parts). I can
use Deltacad to adjust the scale of the image in x and y directions to
get within .020 across a 12 foot drawing, but I have to use an image
editor to take any warpage, skew etc. out of the image.

Once I get a usable 2d vector drawing, I can import it into a modeling
program and design tooling, flat patterns, 3d parts, etc. Deltacad
works much better than the automatic vectorizing program I was using before.

Another thing I really like about Deltacad is the great flexibility and
ease of printing drawings on a large format plotter (or any printer for
that matter). The Oshkosh satellite photo posted here a couple weeks
ago happened to be a really high resolution image. I copied it into
Deltacad and printed it out on 42" wide photo paper. It looks really
nice thumb tacked to the wall.

I used the demo version for about a year before I sprung $50 for the
non-watermark version.

For me, Deltacad is the ultimate tracing paper.

I think it will be quiet around here now. So long.



I WANT YOUR PRINTER !

Printing large format can be difficult. I drew the wing rib profiles of
the Dyke Delta (each one is different) and took them down to the local
CopyMax. It was to big and they couldn't handle it. First of all, it
had to be in PDF format and then it just locked up thier computer.

We finally figured out that we could print it half-size on one of their
printers and then use one of there automatic enlargers to get it to the
proper size. The printout was 8ftx4ft.
