the tolerance is the geometric location of all points which have a %5 distance from the zone line. 50 00:03:22,171 --> 00:03:28,765 According to this definition, the tolerances turns into a semicircle where the zone line ends. 51 00:03:28,812 --> 00:03:36,703 In sections where the tolerances of a zone overlap, the union of tolerances are considered as the tolerances of zone. 52 00:03:36,727 --> 00:03:44,544 Therefore, based on the angle of the two intersecting sides of the zone, a part of the external tolerance zone turns into a curve.
