> Well the depth could become +15, -230, rather than just 245m if there is one entrance 15m below the highest point. You may or may not prefer that - just saying that they could be related in that way.
Yes I agree, there are other ways of thinking about definition of cave depth, but not yet able or likely to be automated using Therion. Although the recent \cave[max|min]z variables are a step in allowing users to customise in that direction. Bruce
