Location of Slope's Section Line

When a symbolic line has to overlapped on a model section line, Revit gives us snap to find exact location of the line except below case.

Of course it's not very important. We can just draw a line at nearest location.
But, I just don't like it. WE ARE ENGINEERS!!!

Ceiling Hangers in Revit

Most of Ceiling hangers have structures like above picture.
Is there anyone make this on 3D in Revit? I suppose not. If not, there must be several ways to describe this especially in section views.

General Methods

Method1 : Using detail lines- just like what we do in Autocad....
                  Why do you use Revit???

Method2 : Make one hanger with Detail Component and copy or array this in a project..
                 This could be the basic way in Revit. But too much works(copy&array).

Method3 : Using Repeating Detail Component.
                 This could be more convenient. But in some projects, many types required.

Method4 : Make parametric Detail family.
                 It works fine in most projects. But under sloped roofs or slabs?
