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:

Have a look at Scan 2 cad

Here is what I would do. Convert the PDF to jpg using screen capture.
Edit the jpg using MS Paint by removing all non relevant
information. That gives the conversion program an easier time of it.
Re print if re scanning.

Here is an example.
