摘　　要：全面讨论平面物体的各种有界平面的全剖切分割，在正向、负向截交线，正向、负向重合边等概念的基础上，论述被剖多面体的有效剖面、截面、新剖面体的形成以及悬面、悬边、悬点等特殊情况的处理，从而实现了平面物体的全剖切运算操作。Complete section of various bounded planes of the plane object is discussed in this papero The formation of effective section, cross section and new section body has been analysed and how to process special situation of suspension plane, suspension side and suspension dot also has been discussed based on the conceps of positive and negative cross section sides, positive and negative coincident sides, so the complete secion calculation of plane object has been realized.
