    Man in .x_t and .sat

    Hey Baldur,
    The . x_t Man is not a solid model. It is a triangel 3D-dxf surface that you can't alter with CAD-Systems. The .sat file doesn't run under my different CAD-Systems.

    Cheers

    Bernd

    sorry guy's, i didnt start checking and converting the 3dman to different cad formats yet. dxf i can import in max, 3ds and max export to dfx but than max wont read these dfx, anyway, newer software versions do seem to get more compatible. i can animate the 3d man drinking a martini in his faforite T shirt in max but for working with more cad systems having him do that on his yacht i better study a bit more...

    The stats on my CAD program (UG) show that the MAN.X_T model is comprised of 56 solids and no surfaces.
    I first coverted it to STL then to surfaces then created solids from the surfaces. Some software will try to covert solid faces to nurbs surfaces during translation.
    I will try to open it a a few different CAD systems and see if there is a traslation error.

    Converting CAD files from one format to another is what I do for work.

    Thanks.

    "convert solid faces to nurbs surfaces" sounds most interesting but also means there is much more to learn here :mad:

    You are correct Bernd,
    There is something wrong with the X_T file.
    It is a solid in UG and MC, but Solidworks brings it in as surfaces?
    :confused:
    I will work on it some more when I get a chance.

    Baldur,
    The process to work via .stl sounds strange.
    Normally a solid consists on well defined surfaces and edges. You lose this definition , if you convert the file into 3dxf or .stl. So if we want to switch a CAD-model from one CAD-system to another we never leave the exchange triangle between .step, .sat and .x_t. This allows us to work with the models in most CAD-System like native files. Acis (.sat) or Parasolid (.x_t) are the kernels of most CAD-Systems for the rest you can work with .stp (Standard Exchange Protocol).

    For small files (up to 5MB) there is a free translation service under http://www.steptools.com/strepo/login.cgi?URL=/strepo/translate.cgi?
    Login as anonymous to switch the data between ACIS, Parasolid and STEP.
    For a long run it would be great for the CAD-community, if there would be the same service via internet for larger files and new versions of the Kernels and STEP-files.

    Cheers

    Bernd

    together with above reply from archnav i got the cad digest newsletter in my e-mail mentioning "CAD Interoperability Not Here Yet, Users Say - in spite of companies' efforts on standardization and vendors' claims on solving CAD interoperability, there is no ideal solution to this problem, based on Kubotek research, Jeffrey Rowe, Advanced Manufacturing, October 2005"

    thanks for the link and will try whats possible...

    Hey Yister,
    Please give me the direct link towards the article.

    Below you found our analyses in relation to the shipbuilding sector.

    Cheers

    hope this works, for me it does. not beeing very proficient in dxf i found it hard manipulating him in different postures and when anyone likes its little effort for me to make a few more positions in max and to convert to dxf

    I guess, Acad Lite can't export in IGES. I opened and exported with ACAD 2004. I think it did convert over 3000 surfaces, thought my computer would crash, but here it is.
    Your guy in Solid Works looks like that:

    SailDesign Old Phart! Stay upwind..

    Hey, Yipster - that's the same guy I use! I had to reshape his head a little so he didn't look so wierd, but he is useful - and he doesn't eat much...

    found the guy in a "man.max" search once as shareware.
    i use this guy daily now and find him very usefull.
    much better than the wooden drawing puppet i had before.
    never saw the need to get him clothed or chance his head.
    here the optimized files i found

    Here you can discover the different between a 3d dxf or 3ds file and a 3D CAD file . The 3D-CAD file you can alter in all aspects in most CAD-systems and you can make 2D-drawings out of the files, related to the edges. In a 3d dxf file you will always see the triangles.

    I have downloaded the file form 3Dcontentcentral
