  • in reply to: Layer Properties: Thickness and weight #36059

    With my old version of FS, I’m asked what unit system (metric or imperial) I’m going to use when I create a new file. Is this feature disabled with the latest versions? 😉

    Anyway, you can check the used unit by drawing a square (each side = 1 unit, whatever unit it is), giving it a thickness of 1 unit, and giving it a density of 1 (like if it was water). Then check for the weight.

    1 cube meter of water weights 1000 kg.

    1 cube foot of water must weight around 60 lbs.

    in reply to: Cat’s and Tri’s #36057

    This is my way, but it’s possibly not the better 😛

    1. I draw the half of a side-hull (port or starboard).

    2. I ask FS to actually draw the other half (not just to show the symetry). This gives me the two side-hulls, but I can see only one: they’re both drawn on the same place (overlaping?).

    3. I move the side-hull off the symetry plane. Thus I get my two side-hulls with a gap between.

    4. I draw the arm(s) connecting the side-hull to the symetry plane, by extruding a part of the side-hull’s inner board.

    The Cataman (twin-hull ship) is done.

    5. For a trimaran (three-hull ship), I draw shorter arm(s) then I draw the central hull by extruding the arm(s)’s edge frontward, backward and downward..

    The Trimaran is done.

    – Draw your ship’s differents parts on differents layers. This will help with sophisticated drawings and use different colors.
    – There are two tools concerning the symetry. One just shows the other half of your ship, the other one actually draws it, knit it to the first half and make both halves an only object.
    – It’s easier to draw the multi-hull ships from the external board toward the symetry plane.

    You can draw non-symetrical ships, too!

    I hope this is clear enough since english isn’t my mother tongue. :unsure:

    in reply to: Add-ons #36043

    I use FreeShip, but I assume this will work anyway:

    Masts: In the tool box, you can choose to draw a cylinder, then rotate it and move it.

    Propellers: Create a new project, draw a propeller, save it as an exported element, open your ship’s file and import the propeller element and move it to the convenient location.

    Deckhouses: My way (but I ain’t sure this is the best one) is to draw and open a hole one the main deck, to extrude its edges upward (in an other layer, it’s better) to make the deckhouse’s walls, For the ceilling, I extrude the walls once more, then I erase the corner’s points and the vertices.

    in reply to: Need help scaling please #36031

    The reference point for scaling (and rotation) operations’ coordinates are (0,0,0).

    I suggest you move your model in order to get the reference point at the center of the interface between the re-scaled part and the unchanged part, i.e. the part you wish to resize must have only positive vertical coordinates and the part you don’t want to change must have only negative vertical coordinates.

    If you don’t want to change the length or the width, but just the higth, select the upper part and move it upward.

    …And don’t forget, The uploaded files must be quite light because the DeftShip server has NOT an infinity of storing space (check for the very first post on this thread). Personnally, I upload only JPeG files, 800×600 pixels and with a size of 100 Kb maximum.
    The DelftShip team is kind enough to allow us to upload pictures just for fun, so don’t abuse!.

    DasBoot: I assume an impportant piont is what’s the vertical position of the Center of Gravity, and this point is known by the shipyard only… if someone does… Anyway, it must be on a quite high position, as it is on any modern liner. Nothing to see with the World War II battleships.


    Are you sure that the line you call an “edge” is really an edge of your model?

    May be it’s just the edge between two polygons (each one on a different layer) and only one being shown (the other being on a hidden layer).

    Hi Michaelf!

    As matter of fact, when I draw my flying-boat, I was thinking of a Dornier’s hull (stabilizating fins) with a Bereiev’s wing (seagull wing).

    I don’t consider the Dornier Whale as a specially beautiful plane, but I think your choice is based on patriotic considerations (“For Sverige, i tiden“?), isn’t it?

    Since you’re interested in my project of kayak with a latin sail, here you have a first sight of it. I draw the man just to make clear the reason of my perplexity about the man’s lign of sight.

    in reply to: Gallego #35468

    Yo tambien puedo hablar español a pesar de que no es mi idioma principal… e ingles tampoco 😉

    That’s why I suggested a few of months ago a PM service for the forum’s members, for we can discuss privately, in other languages.

    Feliz año nuevo a todos!
    Happy new year to all of you!
    Bonne année à tous!

    in reply to: Hull recesses #35418

    Yes, one way do draw a recess is to make a hole, to extrude its countour once for the recess “wall” and once more to make the “bottom” (delete the “bottom”‘s vertices and points).
    It’s a way to draw windows when using an other layer (think of using an almost transparent factor!).

    An other way to draw a recess is to draw its vertices in 2D, on the main body and within its contour, then to move the “bottom”‘s vertices inwards, and finally to enlarge the “bottom” (by moving its vertices or its points).

    I hope it’s clear enough without pictures…:S

    I think the first way is the easier, but I used the second one for a while.

    in reply to: Adding Keel and Rudder to the Hull #35417

    Your imported part appear on the coordinates (0,0,0) (usually the stern).
    Find the place you whish to place it on (check for the points long the hull’s profile) and note the new coordinates.
    Diselect all then ask the MOVE tool to move the concerned part to the new coordiantes.

    NOTE: you can give the part an angle. With the MOVE tool you’ll find the rotation tool. With FreeShip, rotation are made with the point (0,0,0) for center. Then rotate first, then move the parts.

    Hello Michaelf!

    As you must have noticed it, I’m using the Delftship/Freeship software for much more than what it was designed for. I consider this as a way of trainning, of getting “acquainted” with the software… without getting bored. 😉

    I like your arabe saying, and it reminds me a so-called mexican one: “Mañana, amigo! Mañana…” that means “Tomorrow, my friend! tomorrow…”.

    I’m very interested in your Schebecke bacause I’m working on designing a kayak, and I’m thinking of using a Latin rig. But I’m affraid the front part of the sail can block the sailor’s lign of sight. Do you have an opinion about this possible disagreament?

    Meanwhile, here you have my vision of a hull… made for speed! :silly:
    Can you see the slight evolution of the project?

    in reply to: Hull recesses #35386

    Hi Ian!

    Asymetric structures:
    In the layers dialog box, you can set a layer’s content to be asymetric, but AFAIK, this content can possibly NOT taken in consideration concerning the hydrostatics (according to the software you’re using).
    Don’t forget to disable the main symetric button (and to REALLY draw the hull’s symetric part. Use the “modification” tool).
    This is the way I draw a carrier and a prao sailship.

    My english is somewhat broken and I’m not sure what you’re talking about. I draw a sea-plane, too. Beneath its hull, there are surfaces pointing out. Are you interested in drawing this kind of shapes, just pointing inwards?


    in reply to: Show me your ships! #35353

    Question: What part is this ship missing?:dry:

    Answer: Since it’s a prao (non-symetrical ship), it isn’t missing a hull. I just have to add the rudders and anti-drifting fin.:side:

    in reply to: need help with asymmetric hull #35343


    There must be a dedicated button in the toolbar. Using it, disable the automatic symetry.
    Then using the “modification – symetry” command, order the software to draw the other half of your ship.
    Finally, modify the ship the way you whish to.

    I’m presently working on a “prao” ship, too. :side:
    (Excuse me I can’t enable the forum’s URL feature).

    But I’m using the old DelftShip 2.6 and I think I read somewhere it’s unable to manage correctly the asymetric hulls’ stats.

    in reply to: Cant get rid of leak points?? #35342

    Below the keel?!?:blink:

    Do you mean there nothing below the keel, however the error appears anyway?

    Didn’t you draw a part of your ship on an invisible layer?

    Didn’t you try to [knit/weld]1 two unconnected polygons?

    1: Sorry, my english is not perfect 😉
