Right now I have 1 of my graph paper grid squares is equal to 10 blitz units which works well because your typical dungeon corridor is 10ft x 10ft. Hence, 1 blitz unit = 1 foot. The absolute smallest cube you can make is 0.5. I guess it's easier also because it keeps a lot of the numbers as integers so there's less chance for floating point errors?
EDIT: I just realized that if I'm dealing in pure units then having 1 grid = 10 units won't let me get too detailed. I may tinker with changing it to 1 grid = 32 units...makes sense right?
