I’ve created a guitar design and am trying to accomplish two tasks, beveling the edge on the top and scalloping the bottom. I have a line drawn on the top for the bevel and keep selecting that portion of the face and attempting to rotate around axis to bevel that part. Each time I try, it allows me to set an angle but does not make the transformation actually appear. Not sure what I’m missing. Also, I have a curve drawn on the back but have no idea how to carve out that area. I’ve included the file with all my drawings. The model I’m working on is in the lower right.
Without looking at the model (Coffee still kicking in and still in my underwear 
) try using the sweep tool. You could also create a wedge like shape and subtract.
