, And the establishment of the local coordinate system, so that the plane through, and the center is located in the angle between the plane determined by and on behalf of the vector and the negative direction, the initial position in the local coordinate system can be determined.

By the , , and the establishment of the local coordinate system, so that the plane through the center, and is located in the in-plane and the vector, with negative direction, the angle between the local coordinate system, you can determine the initial position.

By, and in the establishment partial coordinate system, enable the plane which is at to pass, also the center of circle is located by with in the determination plane, represents between the vector and the negative direction included angle, then may determine in the partial coordinate system initial

In a local coordinate system established by the,, and, the plane to pass, and the Centre is located within the plane determined by and, on behalf of vector and the angle between the negative direction, then in the local coordinate system of the initial position can be determined.
