Not sure if this is possible.  I have a spherical assembly with reference curves of varying radii going completely around different parts of the object.  Is there a way to have only the visible part of the reference curve be seen?  As it is right now, I can see the entire curve as if the object is transparent.  I don't want to hide the entire reference curve, just have the object block the portions that would normally be covered.  I'm using SolidWorks 2013 SP3.

Thanks.
