    If you have a model in your computer, however inaccurate, export it as a table of offsets and compare it to the one you obtained elsewhere.

    Might give you the clues you need to solve the problem.

    It might have something to do with your intersections.

    if there is no waterplane at zero draft you will get an  error, likewise for the further points fwd and aft for your stations.

    Not needed to use the offset table feature for my work, but tried the technique on a hull I designed with no station at the extreme lengths and without a waterline at the bottom of the hull and found those problems.

    Thanks Maarten,

    I did the same.

    After trimming the hull plates to the intersect lines, I discarded the old transom and made a new surface from the edges, four points at a time.

    One problem when building and ended up with a transom of two surfaces which would not join into one.

    Will join all the hull surfaces into one and try again.

    Thanks Maarten,

    I understand what you have said and now done it for myself on the original model.

    Got the decks, sides, chines and bottom intersects with the transom done and trimmed.

    Still to work out how to get the intersect lines on to the transom to trim that to the shape of the hull plates.

    Tried reversing the process and putting the intersect lines on the transom by nominating that surface first but my first attempt failed.

    All plates are to be developed for NC cutting.

    Maarten,

    I do not know if you received the .fbm file I sent by email.

    My ISP send me a message saying it had timed out and not delivered to [deleted] where you asked me to send to.

    Maarten,

    Still cannot attach .fbm files, it said it was not allowed for security reasons.

    Added 2 files as a trial. First is a .jpg and the second .fbm,  I am getting difficulty adding data files so thought I would see if both attach successfully.

    Maaten,

    Hope you got the file this time. I have no way of checking if the file was received.

    I did send to info@……. as well.

    Hi maarten,

    Tried to attach file intcepts.fbm of 24kb but your forum system tells me

    “Error!File type not allowed.

    Remove this file

    How do I get the file to you please?

     

    Will look further into it myself also.

    Prem,
    You should try a technical college that has classes for Hobbists.
    Personally did a five year apprenticeship and kept formal studying for another 15 years, still have a lot to learn.
    Books are fine but hands on is much better.
    Denis.
