when click on or close to one of the end points of existing segment, it may crash at line 2712 because at that moment selected_points[] may only has one element.
auto dist = selected_points[1].pos - selected_points[0].pos;
may caused by conflict in
if ((pos_2d - win.get_mouse().cursor).length() < 20)
{
dragging_point_index = i;
measurement_point_hovered = true;
if (win.get_mouse().mouse_down && input_ctrl.click_period() > 0.5f)
dragging_measurement_point = true;
}

has_errors will be inconsistent if in the previous line err = GL_NO_ERROR.
Also - all the retrieved values are overwritten by the last one . Is it by design?

Why not to pass through the input instead of an empty frame?

Addressed code review comments and added some extra functionality -

very nice additional features multiple segments and area calculation, real useful.
one more potential issue in measurement.cpp line 347, need to check dragging_point_index, in case a single click onto an endpoints.
if (dragging_measurement_point && dragging_point_index >= 0)
Adding simple distance measurement ability to the 3D view of the Viewer:
