Create a line from another line

Question

The orange line is continuous, but corresponds to the union of several lines.

What I would like to do is to join the lines into a single line until it collides with a green point as shown in the picture.

Is it possible with any QGIS tool?

Answer 1

Dissolve your lines, then run multi- to single-part in order to separate each continuous line from the others, then split lines by points using the green points.
