Hi, use "flags duplicate" in centerline. An example, where shot 1- 164 is excluded from length calculation and shot 1-2 not. centreline # ... flags duplicate # shot data you want to exclude 1 164 52.84 -7.44 12.685 flags not duplicate # other used in lengths calculation shots 1 2 209.70 26.71 5.428 # ... endcentreline Similar behavior can be obtained by using flags surface command, but it is related to surface survey, I think your case is best described by flags duplicate.

Hello,

if I have a leg where I need to separate shots (from the one point I don`t reach a continuative part) and I want to exclude the one from the calculation of the cave-length. What have I to write in my .th-File in the data-lines to exclude it from the calculation of the length but not from the centerline?

I think it is simple, but I have found no idea in the wiki.

Regards

Markus
