Knowing that you are intending on getting C3 from your other post, I would say, if you can, wait for it to arrive. The spline modeler now has a bevel tool in it. While I haven't had to use it myself yet, (still playing with the non-photo renderer! :> ) it's there and may help. Or, try importing into the spline modeler a simple thin version of the logo, then convert to vertex modeler. Then, using litst's method of extruding a small amount of the top level, then re-sizing smaller to make another tier of the model. Turn on sub-division modeling, and watch it smooth out your bevel. :> Texture using the new altitude shader to get interesting smooth shading from the base as black to the top as red. Hope this helps!
