    Hi Chain,
    in the newest development of iges solids are also involved, but a lot of CAD-systems are not able to import them. 3.7MB for the ceramic bowl of the toilet as .igs surfaces is much too large and the presentation even in Rhino is not correct and so you can't use it. Originally the bowl is a solid. Go to http://www.tecma.net/nautica/files/3d/silence_plus/silence_plus.html and i think not larger then 0.2MB. So it would be easy to save it as a solid in .stp-format.

    There are large differences between the geometrical objects point, curve, surface, solid.

    In our models we use normally a combination of surfaces and solids. Surfaces for the hull and solids for the rest.


    Cheers

    Bernd

    Hi

    I find it very interesting with 3D models --- but if I shuld deal seriously with it, it must be somthing not just to display not just to show a fancy picture it must be somthing that reflect in the manufactoring equipment , and there I am critic.

    Once some 15 years ago I myself develobed the applications to take into AutoCAD to draw in another way than AutoCAD's meshes was made, to be able to overcome the restricted numbers of faces you can make in a polygon mesh in AutoCAD, so to be able to unfold the panels --- to be able to make design tools so I could make a true 3D interpalation between two different boats and generate maby 10 different "inbetweens" and point to the one I wanted to unfold and build.

    The result was "Cyber-Boat" as you se at ;

    http://groups.yahoo.com/group/Cyber-Boat/

    But is this enough ----- no a boat is not just panels made with computers ontop a tradisional rigid framework as how made 200 years ago, the framework is the real challance so beside the few other develobments and innovations it ended up with a brand new structural idear please check that at the new Tsunami-Longboat group or at the free download 5Meter - Longboat files at the old Cyber-Boat group.

    Old group ; http://groups.yahoo.com/group/Cyber-Boat/

    Tsunami-Longboat group ; http://groups.yahoo.com/group/Tsunami-Longboat/

    There are more Yahoo Cyber-Boat groups with free plans and various designe, the next proberly be a 2.02 meter true neat pram , one I build several of one that carry 450 Kg. and weight round 22 Kg. you can find it among the pictures in the group.

    Best regards

    outboard engine drawings

    I'm looking for a resource for outboard engine CAD files for design drawings. In particular, HP from 150-250. I wish the manufacturers would have a download link for designers and builders. If you bug them enough they might give you a CD, but I need these now.

    Hi Bernd,

    I also have Rhino, after opening one of the files cleaning it up a bit I get as per attached image. I have cleaned it up so it can be made into a solid. I saved it as a stp file within Rhino, file size 3.9mb compared to 3.7mb for iges.
    If I was to reconstruct the complete model (as there is many individual surfaces) I am sure I could make the file sizes smaller for both file types.
    To test file type sizes constuct a couple of primative objects in rhino (sphere, box etc) and save them as an iges & also a stp, see which one saves the smallest.

    Cheers,
    Cian

    Hey Chain,

    this should be absolutely not necessary and
    All this could be avoided, if it was saved as solids(.igs, .stp, .sat or .x_t).

    So far as I have looked into their presentation, I think they have SolidWorks. This software has a hell of nice converters (in- and output). So they could present us the smaller and absolutely correct file easily.

    Cheers

    Hi Bernd,
    I agree it would be nice if we could be supplied with better cad files, but I am just making the most of what has been supplied.

    Cheers,

    Hi Cain,
    It would be nice if you could upload some 3D-models from your CAD-store towards 3D CAD Blocks and Drawing Files. Otherwise we will run into some problems. The idea is nothing, if there is no action.


    Cheers

    Bernd

    Hi all,

    nobody else with 3D CAD Blocks and Drawing Files, or Documents for the new gallery?

    This can't be.

    Cheers

    Hello,, my name is Gustavo, I am new

    Hi, I put a traveler in the 3D CAD Blocks and Drawing Files gallery, if you need some *.3dm file only ask for it a hull (maxsurf), a block, a righting moment curve (hydromax) any thing, bye and good wind´s.
    For the traveler I use an already drawn block.

    Other 3D-models needed

    I think I have to push the 3D-models idea again. We need other 3D.models under 3D CAD Blocks and Drawing Files http://www.boatdesign.net/gallery/showgallery.php/cat/3054

    The Rhino people can pack the .3dm, ACIS 4.0, STEP and iges file into one .zip-file.

    Jeff, why is this gallery only visible for registered users?

    Cheers

    Bernd

    The 3D CAD Blocks and Drawing Files gallery is now visible to unregistered guests as well.

    I am in the process of creating some solid models of old classic hulls found on the free plans at:
    http://www.svensons.com/boat/
    These are hull skins only. (parasolid or iges format) I will post them when I'm finished. ;)
