| Abstract: | Combining with related geometry theory, space topology relation between lines have been explained. Combining with current lines intersecting algorithm, the hybrid judgment method for judging the only real intersection points between lines has been put forward. On this basis, design and realization of automatically cut lines method can be completed. |
