A while back Survex 1.43 improved the ability of Aven to visualise loop misclosures.
Not only can it colour by error, it can now colour by horizontal or vertical loop error. Unfortunately, the 3d files produced by Therion do not properly write the data. A brief discussion here https://github.com/ojwb/survex/commit/fe8a1b478b91bd977a4b21be49af25724b16c6 92 that identifies the problem. Olly suggests the problem is: -Therion writes 0 for all the horz and vert error values where Survex is being used for data processing. -Therion equates the horz and vertical error to the total error where Therion does its own data processing. For users who want a work around, there is one described in the last line of the thread linked above. Bruce
