[Therion] Drawing the map of a vertical cave

[Jean-Florent Raymond]

Hello,

I am drawing the map of a cave that is so far mostly vertical. In the 
map editor of xtherion is very hard to distinguish which lines / 
stations of the xvi belong to which part of the cave, because they are 
all drawn over each other when seen from above. When adding walls and 
objects it becomes even worse.

Is there an easy way to deal with this? Maybe generating different xvi's 
for the different levels in the cave and drawing the scraps in different 
th2 files?

Best,
Jean-Florent.
