So I've started working on using a pregen to practice setting up a D&D 4E campaign in Roll20. So I chose my favorite, Keep on the borderlands (B2). I wanted to drawup the keep for the players to see how large it is, and so I started to sketch it out, and it just seems so daunting. What is the best way to get the keep into a map, or multiple maps for the players to place their tokens. I need helps.
