I have a line. It is one feature. I want to cut it in two, so that it becomes two features.

When I use "Split Features", after enabling editing, by drawing a cutting line across the line with two right mouse clicks, I end up with 135 segments at once. What am I doing wrong?

I am using QGIS version 3.10.8-A Coruña.

    I don't know, what you're doing wrong, but my split features tool does accept a right click only to finish the split. Maybe you chose the wrong tool? Can you provide a screenshot of the symbol of the tool you're using?

  • Thnx Erik, you are right, only the second click is the right mouse. I am using the Split Features tool with the "scissors and the left grey, right green part of a polygon". Now I am studying the thing, it might have something to do with the fact that the line I want to split is crossing itself many many times... so when I want to make a split on one site, it automatically seems to split on all its intersections.

    Naturally all parts of the line you "cover" with the split tool are then split. You have to be a bit careful.

  • That's not what I mean. I mean that when the line has intersections of its own, it also splits there automatically apparently.

    I think you should provide a screenshot of your line, and where you're doing the split.
