Hi I cant get to print this file, is created in rhino tsplines, I get that issue a lot with rhino the objects dont show on tsplines and only show a shell with no printable layers in cura, but here doesnt allow extension 3dm to upload file any ideas?
i use rhino to model exclusively. i have never had it export a bad model. not sure what you are trying to do with a 3dm file. you need to export as an stl.
