That said, I love this! I posted links to it in an article I posted yesterday to my blog. Great stuff!

So here's another of Dyson's dungeons but this time I added a second 'level' to incorporate the lower floor of his design.
The map, The River Cave, incorporated the basic process of expanding the map into a third dimension but also adding in a "sub-floor" with chambers that were below the main level of the dungeon. Two floors, I would guess, would be a limit on how much you could do with Sketchup and actually be able to show it in the style of the "3-D Dungeon" that we've been developing on here. Any more than two and I think you'd loose the design.
Plotting out the various elevations was somewhat tricky so I had to experiment with things a little. In the above image (colors added with gimp) I started breaking down the map image by marking out the stairs so I could assume that each set of stairs was a drop in elevation (between 5 and 10 feet).
Additionally with this map I decided not to build up and cut out the doors but rather leave them as part of the artist's original design (which I keep as the surface layer).
I've also attached the sketchup file to the post for those who want to see it and manipulate it and all that.
