I guess that was kinda what I'm looking for ... I want to "standardize" my terrain a bit so that human or shorter figures would fit through but larger wouldn't. Afterall you don't build your house so that the 12' monstrousity can come over for tea and cake.
So if I built the door 2" x 1 1/4" (sorry original post was incorrect) would this allow most figures to "pass through". I realize basing may change that.
Or do you just make an assumption that if there is a door that a human figure or shorter can easily pass through but larger figures can't, regardless of the actual size of the door.
