3D corner help

 From:  Doc (TONYG)

Hello. I am brand new to cnc wood working. I have a Romaxx machine loaded with Moi and Cut 3D.
I am trying to draw a gun stock and don't really know how to do the curved corners on the top and bottom of the butt stock. I am not sure which "tool" to use for the drawing or what box to draw it in. (3D I assume).
I realize I might be doing a bad job of explaining the problem since I am not used to the terminology-yet.
Any help would be much appreciated.
