I'm sure there's a way to actually draw a circle, but for your particular use it might be better to use a sphere. If you're comfortable with python scripting, you can use CGO objects. If not, you might do something like this:
fetch 1hhp create thing, resi 24 and name ca # create a new object from some single atom selection alter thing, vdw=10.0 # set desired radius rebuild # necessary if spheres have already been shown show spheres, thing alter_state 1, thing, x,y,z = 50,60,10 # set desired x,y,z coords set sphere_transparency, 0.5, thing # make it transparent zoom ray you can also use something like select + within to select all residues within a cutoff, but I got the impression you wanted a nice visualization.
