Yeah, that's right !!!!! 
Just to help other beginners like me:
[quote="Acki"]No, you can't change the radius of a 3DLine !!![/quote]
Yes, you can change the radius of a 3DLine. The right name of the parameter is "Thickness"
[code] SMaterial mat;
mat.Lighting = false;
mat.Thickness = 2;
driver->setMaterial(mat);
[/code]
All the 2d lines, 3d lines, rectangles, etc. that you draw, will have that thicknes from now on
