Illwinter's Floorplan Generator is a grid based dungeon and wilderness floorplan creator. The floorplan generator can be used to quickly draw and print an encounter floorplan for your favorite pen and paper roleplaying game. It is very quick and easy to create a simple floorplan, you just select what terrain type each square should be and the program fixes the rest. E.g. a cave wall next to a rocky ground will automatically create a jagged wall, but the same cave wall next to a marble floor would create a much smoother wall because this is likely to be an indoor room with polished walls.
Here is a list of some of the features in Illwinter's Floorplan Generator.

• About 50 different terrain types to choose from
