Fabrice, thank you for the hint,
the wiki references are useful but maybe I am still missing something: this is the result I was able to get in LibreCAD



As you can see from the comparison of my drawing with the reference image, the lenght of the upper piece of the plate are wrong (even if the drawing is dimensionally correct), since the lines are drown along an isometric axis

The angular dimension is also wrong (150° is the value in the plane of the paper, but the actual value in the isometric view should be 135°)

Finally the extension lines are not following the isometric axis, but are just orthogonal to the lines in the plane of the paper

As I said, all those things could be fixed exploding the dimensions and working manually, but of course this approach is time consuming and increase the possibility to make a mistake
