Part of my design process for an adventure/campaign area is sketch things out, sometimes it's a relationship map, sometimes it's sort of a storyborad, maps, and other times it's panoramas.

Closeup on one outer bastion.

Going all 10' by 10'grid precision on this would be awesome and insanely crazy. I have to wonder how much mileage I could get out of using these shots and others at the table to explain and illustrate the adventure setting and how much grunt work I could skip thanks to the limited spectacle; do players have to know where the barracks room is inside the outer western foot of the that bastion or would just knowing it's in there do the job?
