[Chimera-users] drawing stereographic projections for point groups in Chimera

[Elaine Meng]

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

<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/hkcage.html>

…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,
Elaine
