Intersection of level plane and surface

How would you show a intersection line showing the intersection of a surface and a level plane or level surface?

Surface Properties -> Analysis tab. Perform a "User-defined contours" analysis:

Then set your surface style to display you user contours:

Yes - the contour method as described will work best on a volume surface where the 0 contour line is the user defined one
