The extracted circumference in every cross section perpendicular to the common datum axis A-B must lie between two coplanar, concentric circles with a radial distance of 0.1.
The extracted line must lie between two parallel planes with a distance of 0.1, and perpendicular to the datum axis D, in any cylindrical section whose axis is coaxial with the datum line D.
The extracted surface must lie between two coaxial cylinders with a radial distance of 0.1, whose axes are coaxial with the common datum axis A-B.
The extracted surface must lie between two parallel planes with a distance of 0.1, which are perpendicular to the datum axis D.
The extracted median line must lie within a cylinder of diameter 0.1 perpendicular to the datum plane A.
The extracted median line of the hole must lie within a cylinder of diameter 0.2 inclined at an angle of 60° to the primary datum plane A and parallel to the secondary datum plane B.
The extracted median line (axis) must lie within a cylindrical tolerance zone of diameter 0.08, whose axis is perpendicular to datum plane A and is at a distance of 68 from datum plane B and a distance of 100 from datum plane C (the theoreticallyexact location of the axis of the hole).
The extracted median line of the toleranced shaft segment must lie within a cylinder of diameter 0.08 coaxial with a line formed simultaneously from the datum elements A and B.
The extracted median surface of the groove must lie between two parallel planes with a separation of 0.08, which are located symmetrically in relation to the datum plane.
The extracted surface must lie between two parallel planes with a distance of 0.08.
The extracted circumference of any cross section perpendicular to the axis of the cylinder must lie between two concentric coplanar circles with a radial distance of 0.1.
The extracted cylindrical surface must lie between two coaxial cylinders with a radial distance of 0.1.
Between R and S and in any cross section parallel to A the extracted profile must lie between two lines of equal distance to the line of geometrically ideal shape, which enclose circles of diameter 0.04, whose centers lie on the line of ideal shape. The ideal shape is defined by CAD data.
The extracted surface must lie between two equally spaced surfaces that enclose spheres of diameter 0.2, whose centers lie on a surface of a sphere of radius 60 and are aligned to the reference surface A. The perpendicular distance of the highest point of the sphere surface from the reference plane A is 35.
