Hi
When fixing up loose ends, we often just create one survey which then contains multiple unconnected centerlines. This is no problem in normal TopoDroid, where sketches can be created for each of them.
However the 3D Viewer always only shows the first one, even connecting the second centerline by manually entering the equation fails because the station could not be found.
Suggestion: Treat multiple unconnected centerlines separately, as if there would have been multiple surveys selected in the UI and also support it in the manual equate dialogue
Thanks
Matt
