i cant remember the code, but i know it is possible. You just have to draw the 2d after the draw of the 3d. im sure if you look at some of the code archives there are a few menu tools etc. that you could use as reference.
However, 2d over 3d slows things down considerably. I might suggest you use sprites as your menu just in front of the cameras FOV. This will allow you to adjust the alpha/transparency on the menus, which you really cant do with 2d overlays.
