Mirek,

   That exactly functionality isn't yet implemented, but you can kludge
it by:

1. creating a model on the fly
2. setting the atom coordinates in the model to the location
3. creating a mesh around the model
4. and deleting the model.

The following .pml example script shows you how to get a 10 A brick
(msh1) or a sphere (msh2) about (2.0,21.0,4.0).  If you plan to use this
functionality often, you should convert the following script into a
Python function with four arguments and place its definition in your
PyMOL start-up file.  This is how you can customize PyMOL to suit your
needs...

# begin example

fragment methane,_pos
alter_state 1,(_pos),x=3D2.0;y=3D21.0;z=3D4.0
isomesh msh1,map1,1.0,(_pos),10.0
isomesh msh2,map1,1.0,(_pos),carve=3D10.0
del _pos
zoom msh1

# end example

Cheers,
Warren
