| Abstract: | A theoretical principle is found through the projection analysis of the parameters in relevant positions of a cutting plane,a quadratic surface and its projection planes,and the demon-stration of the conditions for projected line circle of a cutting plane and a quadratic surface,to re-solve precisely the section line and piercing point and intersection quadric of a quadratic surface.The paper also provides a new method for computer programming and drawing. |
