How to create a radial display around actor

Hi all,

I’m looking for the best way to create a radial display around an actor in 3d space.

TargetingRange

^^ Like this (from EVE)

The idea is that a space ship has a set of radial circles around it, which allow a player to see distances, but also have a view of the XY plane.

My first attempt at this was using a texture and a mesh, which works, but zooming in you end up with a big mesh covering your screen - the idea is that these lines (and perhaps numbers) should be the same size regardless of zoom.
