However, because free curved surface about smallest principal direction of curvature geometry dissymmetry, with between majority situations in only then a point of osculation, therefore needs to cause in the above revolving process by the definite each position to circle clockwise or the countercloc

However, due to the free surface on geometric asymmetry of the minimum principal curvature direction, between and in most cases only a single point of contact, therefore need to be in the rotation process by determining in every location around the angle clockwise or counterclockwise to adjust so th
