What line? You can split a track using the split tool if the line is at the start or the end. Perhaps provide a little more detail so we know exactly what's happening and what you're trying to do?
Not true, tracks display in BaseCamp with track points and you can split the tracks, as you can do with routes. Even the link you posted to explains how to do that.
I never said anything about splitting or not splitting, I simply stated that the 'lines' are not part of the track, a track is only a series of waypoints (or trackpoints), which is 100% true.
Well for most folks a track is both the track points and the lines joining them, and that's certainly how they display both in BaseCamp and on devices.
As I stated above, those 'lines' or 'segments' are temporarily superimposed by BaseCamp (or other device displaying the track) to show the path over time, but they are NOT part of the track.
Anyone can open a GPX tracklog and see for themselves, only the trackpoints are there.
If, for example, you had your tracklog recording configured to save a new trackpoint once every 5 minutes, then hiked a very twisty trail for 30 minutes, you would have a track with only 7 trackpoints, with a grand total of six 'lines' or 'segments' connected them. Each segment would connect a single pair of trackpoints directly, with a straight line, and they most certainly would not be a true representation of the actual twisty path taken.
That is because the GPSr does not record 'lines', it records trackpoints' only. The 'lines' are only superimposed by the software displaying the track to provide a visual representation of the path over time, but not the actual path.
Like Hansel and Gretel, who only dropped pieces of bread to track their path. These acted as 'trackpoints', but there certainly was no 'line' connecting them, Hansel and Gretel had to imagine the path (or line) between them, just like BaseCamp does....
I'm not disagreeing with you that a device only records track points, but a track is the track points and the lines joining them. My original post answers the OPs question.
