This dungeon looks insane

I think i saw this in a perspective view and it was 3D graphic, not really drawn. Still beautiful work.

Yeah those are the ones Troedel mentioned in a different post (over here). I believe that those dungeons, like the one you linked, are 3d models rendered in a top down orthographic perspective.

Edit: here's the artstation page where he describes it in more detail: https://www.artstation.com/artwork/b55Rn

Actually looking at the overhead projection again he must have taken an orthographic shot of the floors and then taken a bunch of different shots of the walls and stitched them together in Photoshop. Which kinda seems like the hard way to do it.... Or... Perhaps he had two different models, the main one which he could take the iso shots with, and then another for the top down shot where he scaled in (or out considering he probably did it room by room) the upper parts all over the place on the horizontal plane (which I think is how I would do it).
