Yep, on my deck plans project, I've found it easier to have certain sections on a slightly different level that other parts of the deck. Here's one such corridor on my WIP plans. This is in the saucer. The upper right on the image is slightly higher than the floor of the lower left and those two thin lines indicate a change in elevation, transitioned by a ramp. The grid overlaid is made of 10' squares.
Not much to see, but the idea does make some sense.
