How to see intersection lines without actually intersecting?

[Kitty175]

Can anyone assist me please with following

I have a sphere-like shape. At certain levels above the ground, I want to cut through it with a plane and use the resulting intersection lines as reference points when building other geometry. Therefore this “intersection” should not affect the existing geometry of the sphere -like shape and thus I don’t want to use Intersection faces function as that will cut the shape and I’ll have to delete the traces manually and that will be a mess.

Thank you!

Make the sphere into a group or component, draw faces to pass through the sphere at the desired heights and intersect them with the sphere. Since the faces are outside the group or component, the sphere will not be divided by the intersection.
