One of the advantages of the Therion cave cartography tool is its ability to quickly change the look of symbology in an existing map. All of the art for point symbols, lines, and floor areas is generated by software when the cave is rendered. This means cartographers can change the look and feel of a map without having to completely redraw it. In this presentation I will show examples of this capability, and discuss the lessons I have learned after several years of using it.
