The coordinate system in UG programming is divided into three coordinate systems: absolute coordinate system, working coordinate system, and processing coordinate system.
As long as the coordinate system is well defined, three points are generally observed:
1. Try to divide into four sides as much as possible, the long one is in the X direction, the wide one is in the Y direction, and the center of the upper surface is Z0;
2. Try to be consistent with the layout of the drawings as far as possible, so that it is convenient to check and review the drawings, and to facilitate the measurement;
3. Place the places that are not easy to process and observable to the outside as far as possible, which is conducive to observing and processing.
