I would like to use QAD plugin to emulate AutoCAD, especially to draw some dimensioning. There are two possibilities to do so: click on 2 points or select an object.
I want to use the object selection on a line with more than 2 vertices, I would like something like that, but with the actual length of the line (currently the length is the one between the start and end points of the line, and I did it manually with the first method) : 
And when I try to use the object selection, I get a result limited by the only two vertices of the section I clicked, as such (I clicked on the almost horizontal section):
Would someone know how I could proceed to solve that?
