    thanks for the program Martijn but cant find that nudging in the manual,
    meaning tollerance by checking leakponts or what is it for?

    have seen it but having trouble getting a squared size grid background

    no hydro on leaking and asymetric hulls i understand?

    how to undo flowlines? when and how to use the locks?

    layers ok but how to devellop plates iff manipulating form curves with more points
    and or splines seems to fragment the red/green dev screen
    (and affects devellopable boundery panels) cant find a tutorial

    interior panels? is that extruding from regular edges inward? how? or do the deckhouse as part?

    import VRML1 or 97 doesnt work for me and did you draw or imported that head LP?

    where is GHS used and .fbm suport instead of uploading zip ?
    here my still leaking drawing that isnt even looking good yet but better
    getting to know the program first

    more questions but meanwhile enjoy the study :D

    Yipster,

    The key thing to remember in avoiding leak points is that each edge must always have [/b]two[/b] faces connectedt to it. Nor more or less. The only exception to this rule is edges lying on the center plane of the hull.

    You can get hydrostatics out of a hull woth leak points, just as long as the leak points are above the waterplane.

    Flowlines can be selected with the mouse and deleted by pressing ctrl-x.

    I'm not sure whether I understand your questions about GHS and developability issues.

    Last time I checked it was still possible to upload fbm files.:D

    Hang in there yipster, you'll get the hang of it!
    It's a fantastic program, but you need to allow time to master it!

    Here's a link to a thread about the building of my first design using FreeShip. Still in progress.
    http://www.woodworkforums.ubeaut.com.au/showthread.php?t=36758

    The main purpose of this project was to gain confidence in using FreeShip. Other designs will follow.

    Thanks goolawah, I’ll hang in there :D sure read the link later


    Martijn,

    control-x takes each individually selected flowline out indeed
    also works on other functions? I’ll try, takes some time to master :D

    how to draw a cat, extend in (from the hull) or outwards centreline?

    played with leakpoints and closed a transom using coordinates

    also just drew some swim platform steps wondered if there is a way to lock a point while manipulating?
    (going to another view selecting that point may result in selecting a close unintended point)

    with minimising leakpoints you mean open edges must close,
    or in other words the points of 2 edges have to have the same xyz coordinates yes?

    below the waterline closing that now rough swim platform with steps seems a big job,
    open the panels, note the location of each corner and bring the various points in numerically or is there a better way?

    Learning by playing around with the program but using the devolapebility check the red area’s seem to get fragmented
    Bringing in more controlpoints, is GHS a maxsurf format?

    Like to try the hydrostatics but first upload the .fbm learn to swim steps

    - If you select a point that point stays selected going to another view
    - joining surfaces must have corresponding control poins up to all 4 digits, centerline points must have an Y of 0.000, I do it manually. Use single piece surfaces as much as possible.
    - Use a minimum of control points at any time and make the control net follow natural lines. Developability looks quite o.k.

    basic hydrostatics, using Rhinomarine:
    Volume 3,632
    Displacement 3.726
    LCB 7,288
    LCB/LWL 0,441
    VCB -0,135
    Wetted Surface 26,887

    getting to understand modeling with subdivision surfaces a little better

    closed a quik drawn test cat and had resistance and hydro

    but after 3 quik try-outs closing a asymetric mono hull centerline up
    i keep gettin a double bow edge and 1 leak point, thats the source?

    trying imports but export is good and it sure is a fine boat program!

    thanks for the advice Windvang, figgers i hope to compare soon
    have to do the shown drawing again tho, get that same double edged bow
    and 1 leak point, better to draw asym from one hull inwards watertight
    moving makes the cat and keeps the calcs (have to check if over 2 hulls)
    rotating to give some camber stops the calcs, i'm learning :)

    And that’s logical, calcs get messed up asymmetric I think

    better to learn down to the bottom of a mono first
    but impatious as I am here some questions over some not so clear things on a cat hull

    have a test cat file with all calcs working but a check takes them out, hmm..

    cats file underwater area shows flat in michlett

    And testing the M2 JMN cat from the design database gives a access violation trying to export to michlett

    don’t understand yet why some edges don’t select sometimes or don’t want to be in a triangle

    Smallest ok hull I drew in 4 triangled faces and wondered if there is a hint how to unfold to a leak and double edge free check?

    Chancing waterline don’t but dimensions do throw calcs out?

    Nurb I read in the manual ( like I used to say ) should be nurbS even one nurb is a Spline

    KM is kilo moment or something? “KM” not found on the forum, is gravity arm right?
    With calcs on by a cat over 2 boat lengths up in the air it shows

    Mouse wheel (zooming) sometimes hangs or what?

    Arrow keys also move a selected point (handy in other viewport)

    probably doing something wrong but learning
    just sharing my experiences here with mr brains great freeship

    now reading the manual 2e time following the right syntax
    a cat, even an asymmetric tri gives calculations


    cat underwater stations doe look strange in the michlett file generator tho but I talk way to much and better do it right

    Hi Yipster KM is the metacentric height.

    hang there yipster you will get it right as you mention maybe practicing with a monohull may help you get onboard with freeship, i haven't try it myself modeling a cat but maybe if you try firts just modeling the hull (cat) without the house it may help too.

    cheers

    thanks for the KM help CGN and if you do try a cat RTFM ( Read The Fu**ing Manual ) page 44 and mirror and it works like a dream :)

    mirrored, moved, scaled and edited now instead of drawing in or out from one hull
    am i trying to find mazes in access violation in this great given horse or is it possible ?

    Yipster,

    Two important remarks:

    First of all, your main hull is still decalared on both sides. You can safely delete that part of the hull that is on the opposite side of the centerplane than your outrigger. (port side in your case)

    Second: FREE!ship likes the controlpoints to be on pot side, so you'll have to scale your model in transverse direction with -1.0 do get it on the other side.

    Did you really encounter an access violation? If so that'd mean sloppy programming:D
    Can you reproduce that message?

    You mentioned an access violation????
    Is that reproducable?

    Plugging the leaks

    Just a few double edges. Here is your Trimaran
