[GIS] How to split a segment into two segments

qgis

The problem is how to split segments or in other words how to insert new points into a polygon so that the segment where I created the new point is now two segments connected by said point. Every time I create a new point within a segment, the segment stays the same length as before and is not being split by the new point. (I don't know why the following snapshots have double columns on the left side but just ignore that. was not like this in the program). First I have the segment I want to split:

segment is dark red between two points.

Then I go to edit mode for the segment layer, click on the knot tool and select the segment:

location where the segment should be split.

I double-click on the segment where i want a new point. The "new place for the point" appears:

enter image description here.

I then go to pointlayer, activate the edit mode, click on "add new element" and create a new point near the segment:

new point is shown near the "x".

After I activate the snap-function and define the radius, I place the point on the "x" with the knot-tool:

point is now in the right place.

Now if I go on the info-pointer and click on the segment, the segment is still as one piece and is not split by the new point:

still one segment.

Why?

Use the Split Features tool in Advanced Digitizing toolbar.

It seems like you just added new vertices. Adding vertices to lines does not split lines and it shouldn't. That's a different use case.

I didn't not understand your reason for the point layer. You might want to elaborate on that if it's important.
