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