The Line Distance tool allows you to measure the distance between two points using straight lines.
To use the tool, as shown in the figure below, access Network Tools through the side menu and select "Online Distance".
This changes the mouse arrow to a '+' and you can click on the map to add points, drag existing ones to reposition them, and create vertices between these points by clicking on the transparent squares between two points.
It is important to remember that the distance indicated in meters will always be the total distance between the two ends of the route, considering the path taken through the points.
To cancel, just press Esc .
You can also calculate the distance between two elements in the project, for this see the article on Metrics.
