Paul,
I have a set of RC giant scale plans which came online as a
pdf (raster). What would be a good program for converting
bulkheads and ribs to dxf for a CNC router?
I'm following the Rhino posts, very interesting!
Thanks,
JimR

Good question. I don't know the answer.
Sounds like some kind of scanner program that can detect
lines.

Rhino can put a picture in the back ground but then you must
manually trace it.

Send me one of the pdf's.

Thanks for all the replies. Attached is the pdf:

Being a messed up old grease monkey, I figure a 20B p-ported with the DD15 TC
system should give over 500HP easily. In a 3/4 plane with two engines should
be a rocket.
