I am doing research with calcium carbonate structures. I need a way in which I can familiarize myself with the lattice structure of calcium carbonate polymorphs, especially calcite.
I really struggle to see things in three dimensions. I borrowed an atomic model kit from my professor and that worked out OK, but I still wouldn't be able to tell which is the $(101)$ plane, for example.
I tried downloading software such as BallVIEW, but I found it quite confusing. I need something in which, I can load the structure, and then it can tell me where each $(hkl)$ plane lies. I don't know how to program so I would really appreciate it if anyone can direct me to something user-friendly.
