This paper mainly discusses the oblique line and the oblique plane as well as the ways to exam -ine the visibility of their intersection in the descriptive geometry and mechanical drawing teaching .It con-cludes that using auxiliary plane and the conversion surface methods to find the intersection and adopting the method based on double point to examine the visibility are two reliable , simple , accurate , easy and novel methods .
