Hi Elaine,

thanks a lot for your response.

have a nice week.

Hi Arvind,
The most similar thing is to draw a surrounding icosahedron framework of pentagons and hexagons with the Chimera “hkcage” command


…but it does not put each hexagon or pentagon on a separate stick like in the image you sent.

In the command, you specify the values for h and k (T = h**2 + hk + k**2) and optionally radius and orientation.
I hope this helps,
