I've been using Revit for a few years now. I've delivered a handful of projects using it. I can make flexing families, use parameters, make a dot matrix door schedule by programming calculated values into the schedule....

I can't understand how underlay is supposed to work.

It's never a useful view.

It seems to me like it's a different level's plan, shown using the cut plane and upper/lower limits of the view you're showing the underlay in.

Why isn't underlay just an underlay of another view, exactly as that view shows natively? This is what I need. Not, ....whatever it's doing now.
I know, I know, "why don't you just put two views over each other on a sheet?" - because that means I have to go make a junk sheet somewhere, when I could have a tool to just overlay views.... you know, like mylar.

Ok, for those of you with hair, Mylar is a transparent plastic film that Architects used to draw on. It's how AutoCAD got layers.

It is only useful if you use linework to select object you want to appear in your drawing. For instance roof above in hidden lines.
