How can I hide a sketch spline frame

For illustration purposes, I have drawn a spline in a drawing, to illustrate a power cord.  However, the frame that controls the spline also shows and prints.  I cannot find how or where to turn that frame off.  A search of the drawing forum does not show a single message with the word "spline" in it.

I get too many hits when I search the help file to uncover the right page, if it is there.  Perhaps "frame" is the wrong term to use with SolidWorks to describe what I want to turn off.

Any ideas?
