Digitizing drawings of an old sailing yacht

    I have line drawings and some hull plans of an old sailing yacht, and would like
    to digitize the drawings that I have. The result I want is: plots of the frames,
    etc for the construction of the boat first at a scale of 1:10, and then the
    real size maybe?!? :)

    The yacht's actual length is supposed to be 24meters.

    Can someone recommend software to help me to digitize the drawings and
    get a 3D form for the hull, fair the hull, and then get drawings of the frames?

    Thanks very much for your help.

    if i understand correct you have the files already in electronic format, bmp or jpeg etc...then just open them or copy and paste into most cad software, turbocad, autocad etc..

    is very easy, you just trace on top of them, once you have them on the cad screen, it will be hard to get a nice lines out of a software that converts raster to vector, there is some software really good but the price is really high and still for construccion you will need to "rebuild this lines", so your best bet, i guess is to copy and paste the image file into a cad software and trace on top of it, then inside the cad sofwtare fair the lines, it takes a while but not impossible.

    good luck

    The approach we take with Maxsurf is to scan the lines plan so that you have a .bmp or .jpg file, then import that as a background image into Maxsurf. The image is scaled accurately within Maxsurf, typically by specifying the distance between stations or waterlines, then Marker points are placed as accurately as possible on the lines.

    Marker points are three dimensional, so if for example you were creating points in a body plan view, you would set the longitudinal position of the marker and then click on a section line to create markers for that station position.

    Once you have a 3D set of markers you can then use them to manually fit a Maxsurf surface, automatically fit a surface using our Prefit program, or automatically fit a surface using our Genetic Algorithm based fitting function.

    hope this helps

    I did this just the way described above, except with Rhino. This was a Ted Brewer design that I bought paper plans for and wanted to digitise. Scan, background, trace, scale, loft surface. Results in my gallery.

    I have never used Maxsurf but I understand it has much more powerfull surface lofting systems.
