Ahaha...

Though granted, this image is kinda cheating since it's a multiplayer level, which removes a lot of scripting stuff you'd need to play a single player level

>They have no height (but they have width and length), so you don't see a thing if they're laid on their side in the air. Fairly ingenious system to make a 3D arena.

Erm... Not really. It's probably best you just follow what >>720906 said. Ignoring the 3D floors aspect, think of Doom editing as taking a giant, solid block of level and carving out chunks of empty space, which eventually becomes the actual level that the player interacts with. You create length/width with whatever shape you draw, and height with the floor/ceiling height parameters of the individual sector.
