I find that really great and I want to keep it.</div><br><div style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt;">However, I received several remarks from my co-cavers/surveyors that this is not quite readable, and that they would prefer if I can also add the depth since the entrance at those points. I can do it manually with the point label, but for a complex system, that will be a pain to maintain each time we add a new survey or a connection with an other cave previously unconnected.</div><br><div style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt;">I thus tried to add a new user defined point (u:prof) based on the present altitude definition.
