    Eraser: Pink Pearl.
    I imported a graphic into AutoCAD (a jpg I believe) and it put it on 0
    layer.
    Had to spend a lttle time *scaling* the image to get it real close to just
    right.
    Then, on my regular layers I drew what I was intending.
    Basically, I used the stuff on Layer 0 as a Template for the thing I
    actually drew.
    Then, turn off Layer 0 and send the rest to the printer/plotter.
    Been a coupla years since I did it.
    The inherent problem with scanning stuff is the background noise as it
    clutters the new output.

    Not really, as most of it gets wadded up and thrown in the corner.
    It a simple vehicle for quickly getting ideas from brain, through hands onto
    paper.
    I've used miles of the stuff.

    In a case like Jojo's I'd tape the original sketch down on the table and
    roll a new section of bumwad out over top of it and sketch the new garage,
    additional 2', whatever on the new piece. Then I'd bust out the surgeons
    tool, the xacto knife, and perform dual brain surgery on the whole thing,
    yank the inappropriate parts out and scotch tape the rest together. Then I'd
    plop that frankenstein down on the copy machine, pop a breath mint in my pie
    hole and ta-daaaa....ready for another powerfully stunning client
    presentation.

    If the client was running late for the appt. I'd stretch another piece of
    trash over top of the one I just completed and grab a black flair and whip
    out a quick 3d rendering with landscaping, just to guide the clients
    imagination in the right direction.......

    Either that or a dull yellow crayon on a crumpled up brown lunch bag.
    Seriously, wintopo works but like many (not all) freeware programs
    involving raster to vector and raster to character... you get what you
    didn't pay for. Most leave you searching for something better.

    Absolutely!
    Inkscape: http://www.inkscape.org/
    Autotrace: http://autotrace.sourceforge.net/
    Xara XTreme (free for linux) might also be able to do it as might other open
    source vector programs.

    I'm trying to instal it in Win98SE. I see that it can be done, but can't
    find out how it is actually achieved.

    Seems to be a file 'Install' missing from my download.

    Your going to spend as much time scanning and massaging and redrawing, as
    you would jsut drawing it right away. Might be better to just do raster to
    raster and get him either a Tablet PC or a tablet for his existing PC. It
    has a bit of a learning curve but it will look more like a sketch than any
    vector drawing. Sketchup is a great design tool. Often I input an autocad
    drawing in there and change the roof or add something to see how it would
    look. Its not hard to learn, and you could import a 2d raster that you can
    trace, or even use a 2d raster as a texture for a 3d polygon in sketchup.

    I don't understand how you could keep something looking "sketchy" using
    vector drawing. Keep it raster and even just using the erase tool in
    photoshop and print it out for more hand sketching would be faster.

  10. The best software I have found for this is Scan2CAD,
    (http://www.softcover.com/)
    It may be slightly overkill for this application, but it gives the best
    results of any of these conversion programs.
    Be aware though, that successful high quality conversion requires some
    tweaking.

  11. Sorry, forgot to mention that they do a 14 day fully working trial,
    after which it still works as a raster editor. Which is perhaps just
    what your boss wants?

    We call the roll tracing paper "talking paper". I even use that term
    with my family and my boys know Mom needs paper and pencil. My dad was
    a draftsman 60 years ago and he uses that term as well. Maybe the terms
    are regional.
