    Hello everyone,

    Can someone here please tell me how to create geometry so that when I export it in .STL file, it doesn't appear like number 2 instead of number 1 (please see attached image below)?

    Thank you

    You can't. STL can only approximate non-planar surfaces by dividing them in to many separate polygons. If you set the resolution higher when exporting you will get a file that looks more like 1, but it's never possible to get it completely smooth, though. But usually the resolution of the printers is lower than the resolution of the file so it doesn't matter that much.

    Shapeways does now support OBJ which is common and I believe nurb based (Allows rounded faces)

    Do you know how that works out when converted to the printer file format?
    (second time i've seen nurb mentioned in as many days - i gotta do some research into this and catch up with modern stuff)

    @srirg60 - for smooth printed round shapes, I aim for triangles with 0.1mm or less between vertices, which works for me :)
