I work with crystals at my job (think diamonds, rubies, etc. but nothing so expensive) and I use a software known as Diamond crystal structure visualization which generates 3D renderings of the atomic arrangements of the atoms in crystal structures. It has all of the xyz coordinate data to produce 3D design files that would be printable, but it isn't formatted to save in any file type that is recognizable by typical design software (SketchUp, MeshLab, netfabb, etc.) If anyone has any ideas about how to go about importing this data, I would greatly appreciate it. I know I could just sit down and put in each atom by hand as spheres and connect them all with tapers, but the scale I want to use would take forever and if I already have the xyz data, I would rather just use that. The Diamond software is available as a demo download on their website, so if someone has the time (and inclination to help), you can download it and see for yourself. Thanks in advance.
