This option identifies approximately when the curves or surfaces vary their direction at a given angle. It may be useful for splitting strong curvatures, so the meshing-analyzing processes should be simpler. The command only shows the points where the curves varies the desired angles, but it also asks to the user whether the detected points must be added to the geometry or not.

The command only asks for the desired reference angle (in degrees).

The following figure shows an example of application:
