Revit: Ramp Rants

We all love ramps, right? At least, we have to tolerate them when designing buildings that have ramps for one reason or another. Let's now ignore, for a moment, the usual issues about the nonfunctional up arrows and the lacking ability to join walls to ramps; I've got something even better this time.

Let's say I want to model a ramp leading down into a parking garage. I model the ramp with some additional walls next to it, and a cellar wall under it. All looks fine in the 3D view:

But what happens when we look at the ramp in the plan view? It's not a pleasant sight:

The ramp isn't properly rendered in plan views; in fact, it's rendered as a flat slab lying slightly above the bottom constraint specified in the ramp's properties (you can see that the ramp edge casts a shadow even though the lighting settings have a ground plane specified at the bottom level). Additionally, the wall that should be obscured under the ramp is now completely visible on top of the ramp-slab.

Use tilted Floors instead, you say. Seems that's the only option for acceptable graphical representation, and it's not like the ramp up arrow works anyway. This time I'm lucky, but next I'm going to have to model a curving ramp...
