It would be really usefull to have a function to expand a crystal periodically in the 3 directions (now this is possible only with a .cif file I think). Thanks a lot !
Thank you for the suggestion, @Cyril !
Yes, for now, it is possible only with an importer for crystallographic .cif files. There is a possibility to replicate crystals thanks to the Crystal Creator App, but it does not expand them periodically with bond connections. We will see what we can do.
