The Right Plane bisects my model.

I need to create a sketch on that plane.

The elements on this new sketch will rely on some of the existing elements the plane intersects.

How can I cut(in display only - i want no cut feature in the tree) on my sketch plane so that I can see the internal existing elements that my new sketch will use?

I do not want to rely on Display State because that shows a jumbled mess of hidden lines i don't want to wade through.
