[TheForge] Question...Illustrations

[Walter Mullett]

Bob,

You can do the same thing with AutoCAD.  Just insert the image file and work
over top of it.  They used to have a cad overlay program which allowed you
to work in the raster file adding vectors and deleting raster information
but I don't think I need that since I can insert the image.

But I think this thread started with how do you convert an image to a
hand-sketch look.  There are several programs that will do this from a cad
vector file and I'm sure Photoshop will do that as well.  I use ArcSoft's
PhotoStudio.  Not as powerful as Photoshop but it will convert my line
drawings to a sketch look and it does a nice job with other images too.

Walt

Andy,

Jerry Hoffmann taught a seminar for BAM a couple years ago on how he creates
the "Blacksmith's Journal".

He imports his scanned drawings into a Vector based drawing program
(Inivision I think). He then uses an overlay to recreate them as vectors on
top of the original.  Once done the original is discarded and the vector
drawing is used.

I saw this done using Corral Draw many years ago, but it was at a computer
fair of sorts and they were going for the WOW effect and not teaching the
techniques. They gave the impression that the program could create the wire
frame drawing by itself.

I have AutoCad and it's on my list of things to try. Not much CAD work
latelly, so I haven't been into it.

If you find a way to convert automaticly please post your solution.

What you can do is use a define edges type of filter and convert the result
from raster (grid of pixels, what Photoshop works with) to a vector
(mathematically defined lines and fills, what illustration programs, like
Illustrator or Freehand, work with) format. This can yield line drawings
that can be adjusted before use and can be scaled to any size with no loss
of quality . . .
