I've created a .wrl file using a program called NetLogo3D. I'm using Linux, so I am able to view the file in 3D with no problems whatsoever using whitedune. I feel like my file fits all of the guidelines, but it is unable to upload to the website because of a "Calculation Error." It obviously couldn't be fixed automatically, nor could it be fixed via the manual fixing process. I emailed the Shapeways team, but they couldn't even open my file. So, not only was it not fixed, no actual problems were reported, so I am clueless as to what I need to do. If you all could help me out at all, it would be GREATLY appreciated. Thank you in advance!
