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
