[Chimera-users] drawing spheres with various radii

I was able to draw the sphere using shape sphere. Now having troubles with changing radii of sphere (to specific length in Angstrom) and changing center of sphere (to a specific atom). Could you advise me on that.
Sorry for bothering you again,
Thanks for your time,
