    Getting restless with my retirement I decided to play around with FreeShip vers 3.3 I downloaded many moons ago but never had time to fool around with it.

    The manual is very poorly presented and not very user friendly, especially at my age when one do not fathom new software procedures and jargon all that well.

    Decided to do a basic hard chine boat and got on well to the point of the screen print attached. No way do I get the transom to fit.... Busy the last two days and when things happens, it is all haywire and back to start.

    Can anyone please explain to me in simplest terms step by step how to proceed from where I am to get the transom fitted. Did created a layer for it but do not know how to get it all together.

    Thanks for any help forthcoming:cool:

    Wynand,

    after you have created the new layer for the transom (not necessary, but a good idea) extrude the aft edge of the hull (i.e. all lines that are the outer edges of the transom) to some distance aft (say: 1 metre).

    Remove all control lines, then all but one control point on that new surface so that you end up with one line from the upper corner of the transom to said remaining control point and another line from that point to the lowest point of the transom at the centre line.

    Now move the point from aft of the boat to the transom plane (i.e. x = 0) and make it a "sharp corner".

    VoilĂ , a closed transom!

    Hope this helps...

    There is an imo much simpler way of doing it. Just follow the 3 simple steps shown in this pic:

    Cheers

    P.S.
    Sorry for the bad quality of the image. Looks like JPG compression doesn't work well with the colors I have choosen for the text :( But I hope it is readable enough.

    Thank you guys :cool:

    Daiquiri, I tried your method but when I made the new face, the transom lines goes beserk.....:( unlike your pics.

    Olaf, tried yours as well, but the aft edge at transom corner do not want to extrude unless I highlight the sheer partly to next control point, hence extending two lines out making it difficult but your method did gave me an idea and it worked like a charm, tested it on other hulls and goes like this.

    With the control net active I just highlighted the transom edges (top panel, chine and lower panel) at aft, click the top aft edge control point on sheer and extruded a meter in traverse plane (minus value) and connect the control points to centre line. Switched on the interior edges and clicked them all with transom edges and made new layer. Shows up perfectly in plate development as well.

    New battle - creating a deck, will keep me out of harms way

    That is pretty strange, because that's how I use to do it and for me it works 100% of times. Could it be that one of the points you had picked belonged to the bow instead? It is pretty easy to mix them in the body plan, and the resulting face can look pretty weird indeed. Much safer to pick the points in the 3D view.

    And I use pretty much the same method for creating the deck, by the way...

    Cheers

    Daiquiri, this is what happens when I put a new face on the 4 control points shown in your pics.

    The bottom and chine plate at transom edge disappears and I definitely clicked the correct control points.:confused:

    Nevertheless, thanks for the tip on deck. Will try that tomorrow

    Aaaaahhh, ok! Now I see. :D

    Yes, Freeship will automatically transform all edges which connect the new face to the old ones into "soft" edges (grey color). Same for the points, which are transformed into rounded corners.

    Here is what you have to do. Once you have created a new face, as described in my first post, you have to select these "soft" edges and points and transform them into "crease" edges (thick red color) and "corner" points.

    This is how you do it:

    Transom.jpg

    That will cure the problem. :)

    Cheers

    I think Olav meant to say transverse rather than aft. To me the extrude command is the better way. Once that is done, [ctrl] clicking the new control points along the edge of the transom and setting the Y value to 0 (zero) will get things in line in a snap. Extruding decks is the same principal, however your deck will have the same shape as the shear initially so it will take some work. Once you extrude the deck... you will not be able to extrude the shear again for anything else though, at least not in that same spot. Unless you plan on flipping the model upside down, you may wish to create a deck which isn't extruded directly from the shear. Here is where you can start your .part library. To create a panel that is physically separated from the hull you will need to extrude a section of the shear vertically. Highlight a contiguous section of the shear and extrude it upwards a little bit. Immediately extrude it upwards again by a larger margin... several units (feet or meters, whichever you are using). Turn on faces and highlight the grid that represents the little extrusion. Just the grid. Delete the grid and you have a panel that is physically separate from the hull. Assign it to it's own layer. I would suggest flattening it first, then deselect all, highlight the panel grid and export it as a .part. Now you can import that same panel into any model you create, and use it to make decks, sails, bunks, bulkheads, etc.

    edited to add... after re-reading things... I understand what Olav was suggesting. A different way of looking at things but I expect it could work.
