I'd like to make a nice molecular model of the theoretical assembly of an icosahedral viral capsid in chimeraX from the structure of a monomer. I do not think chimera can do this alone, but how would I prepare a file to visualize this assembly in chimera? What software/steps do you use?

Specifically, if I have the expected dimensions and icosahedral triangulation - 30 nm diameter and T = 3 - as well as the coordinates from a PDB file for a virus's capsid monomer, what is the (easiest) way to make a coordinate file of the capsid assembly?

Thanks for any tips/tricks!
