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.
