The tool for measuring the Cobb angle in degrees is accessible form the button (7) and selecting Cobb Angle from the list. The measurement is done manually. Two points are marked with the mouse, forming a line part of the first side of the angle. Then two other points are marked, forming a line, part of the second side of the angle. The vertex of the angle is visualized next to the first drawn point on the first line. It is possible to move any of the points on the angle. The measurement result is recalculated in real time.
