| Abstract: | Intersect line drawing is one of the most difficult parts in the engineering drawing teaching.The lack of correct understanding of the shape of intersect line of the students is one of the reasons that cause that problem.This essay describes several mathematical analysis methods of intersect line by the way of analytic geometry,and mainly discusses the shape of vertical shadow. |
