fillet?

i'm wondering why i can't fillet the faces on the top and bottom of the neck or body of this guitar. can you please take a look and let me know?

also on a side note ,are there plans to add a draw on surface and cut-extrude option?
it would also be nice to have a checkbox beside the hide tool for show/hide 2D & 3D independantly.
