I'm completely new to Blender, and I have been playing around in it to create some atomic-level models of crystal structures. I've been using the Atomic Blender add-on to create spheres for atoms and cylinders for bonds.
I would like to create polyhedra as well, so I'm trying to figure out how to add planes between atoms. Is there a simple way to create planes with vertices located at the origins of the spheres?
For reference, in the image below, I am trying to make a triangular plane between the selected spheres.
Furthermore, if there's a way to add planes in a more automated manner, that would be great to know too.
