    hi.

    i'd like to know the setting of SHM_STL exporter with Lightwave3D.

    It has "Binary" or "ASCII" in Type. Which should i use? :eek:

    Hi Akira,

    We support both ASCII & binary encoded files.

    Please let us know what your experiences are. You can sent any comments to service@shapeways.com.

    Best regards,

    Robert

    hi Robert, ty for the response.

    i created one simple box, divided into triangles in Lightwave3D.

    After that, exported it with STL using SHM_STL exporter and uploaded to the site.

    However i gotta e-mail says "The model could not be validated. "

    What else should I do?

    Your box should be ok from the looks of it. :D

    Would you be so kind to sent the resulting STL file to service@shapeways.com?

    I can then analyze the issue more thoroughly.

    Thanks!

    Robert

    Hi Akira,

    it's probably the size of the model that's causing this problem. Our STL import is currently interpreting 1 unit as 1 meter, and that can easily exceed the maximum print volume of our printers.

    Try scaling down your model by a factor of 100 or even 1000 and see it uploads correctly.

    Cheers,

    Bart

    I was just thinking. Can you check if the normals are pointing to the outside?

    That could be a reason for the failure.

    Best regards,

    Finally i managed to upload my simple box model.

    Creating a box with Lightwave3D and subdiv into triangles.
    Then export it as a "OBJ" file.

    Convert "OBJ" file to "STL" with MeshLab.
    (i tryed "3ds" from Lightwave but it failed to open with MeshLab.)

    That's all.


    i haven't tested any complicated model yet, but hope this information will help Lightwave users.

    Hi Akira,

    was the triangulation required to get it uploaded? Our server should triangulate the mesh automatically - I'd be interested in hearing if it didn't

    Cheers,

    i'd trianglated before uploding.

    but i guess it's useful for beginners if server triangulate automatically.

    Hi Akira,

    yes, that was my point ;) Our server *should* triangulate automatically, so I was wondering if you could get your file uploaded without triangulating it yourself.

    Cheers,

    Bart
