the easy way is to use MathGL3d from

and send the lines to the MathGL3d window with a 

MVLineTubeSize->any number

option. You can still adjust the tube radius interactive
in the visual parameter panel of MathGL3d.

You *can* use Thickness[] in 3d plots with

gg = ParametricPlot3D[{Cos[phi], Sin[phi], 1, Thickness[0.05]}, {phi, 0,

you will get a thick line.

To get the polygon out-line you have to tranform the polygons
with the WireFrame[] function or with

the rule 

yourGraphics3dObject /. 

Or if the polygons should survive the EdgeForm[] 
function will do it.
