# How to hide part of intersection in Solidworks?

I have imported STL into Solidworks, converted it, then built an intersection of this body with a plane. I got 3 objects: first half of a body, second half of a body and an intersection ellipse.

I can select any of these parts:

On this picture I have selected one half and hovered ellipse.

I would like to sketch in a plane, having this ellipse as a reference.

Unfortunately, the halfs of the body occlude sketch for me. Hence I would like to hide them, but can't: deselecting eye icon hides entire body and an ellipse.

How to accomplish?
