Two things come to my mind: 1. I also often use aven to assist my drawing. What helps me alot here is linux/kde, because I can do stuff in aven, put the window below xtherions and make the xtherion window transparent. Aven works as a kind of „background image“ in that regard.
2. when drawing vertically, isn‘t drawing (and rendering) exendet elevations far more useful and expressive? You also can export xvis in that projection. > Am 28.01.2025 um 17:17 schrieb Tarquin Wilton-Jones via Therion > <[email protected]>: > > Hi Jean-Florent, > >> I am drawing the map of a cave that is so far mostly vertical.
