Xavier I did have a project that distorted part of a loop 400 m vertically too far downwards. Changing from Therion loop closure to Survex loop closure resolved the problem, and so I have retained that setting ever since. That may have been in 2013, or maybe earlier. On a few occasions since I have checked to see if that problem still manifested, but it did not. I never figured out why it did it for only a window in time/Therion versions. Bruce

Well, on my side, my projects with multiple fixed points with uncertainty that were compiling last years are now generally crashing at compilation. However, since I changed computer, therion and survex version, it is difficult to single out the reason. With no loop and several fixed points with uncertainty, it seems to crash systematically like in the example I posted. When it does not crash with multiple loops and multiple fixed points with uncertainty, it can either gives a .3d output that seems reasonable in aven, or it can displace one of the fixed points kilometres away, either in horizontal or vertical direction! Just fixing a point at 950 altitude can output a 3d file where the altitude is at -4000m.... A new way to explore abysses! I have just looked at the .3d result so far since I have not drawn all the maps yet in the cases where it compiles. As soon as I manage to set up a mock-up example, I will post it to document this amazing behaviour.
