website blurb:
Dungeonographer is a map-making software program designed to easily make dungeon, building interior and cavern maps. All of the artwork typically needed for fantasy maps is built in, drawing lines is easy, and the software manages to keep everything in layers without much user intervention. Some artwork for futuristic maps is also built-in.
Basics
Easily change tiles by just clicking the hexes.
Drag over tiles to change them more quickly.
Use map item icons to add doors, beds, bookcases, chairs, etc.
Draw lines to add walls. Lines can easily snap to corners of squares or to 1/4, 1/2 or 3/4 of the way across or up-and-down the square.
Add notes to any square to detail the contents of that room/area.
