摘　　要：基本体不同、截平面与基本体的相对位置不同,导致截交线的多样性,使截交线的作法成为《机械制图》的一个难点。详细介绍了截交线上点的选取方法以及这些点的第二面投影和第三面投影的求作方法,并运用此方法对平面立体、曲面立体和组合体的截交线作法进行了验证。实践表明此方法提供了一种清晰的思路,使初学者非常容易掌握各种类型截交线的作法,对教师的课堂教学也有一定的参考作用。The difference of basic bodies and relative positions of cutting planes with basic bodies will lead to the diversity of intersection line, which makes drawing intersection become a difficulty in＂mechanical drawing＂. This paper summed up a general method of drawing intersection line rapidly and accurately. This method was verified by the intersection lines of plane bodies, curved surface bodies and complex bodies. The practice shows that the method provides a clear idea to make the beginner master various types of intersection approaching easily, and also plays a reference role to teachers.
