If you really want to trim your plot with a cylinder you can try to
adapt the principle which is present in the "SurfaceColor" example in
the help browser.
To get the line drawn on the surface, first convert your plot to a
generic graphics (Graphics[....]), then type %//InputForm.
You will have the internal structure of the graphic. Then, with
replacement rules, you can keep only the part you are interested in.
You can try something like that.
