| Abstract: | A theoretical foundation is turned out,through the analysis for the projection of parameters of relative positions of a cutting plane,a quadratic surface and its projection planes and the demonstration of the conditions for projected linecircle ofacutting plane and a quadratic surface,to reslove precisely the section line of a quadratic surface,And it also provides a new method for computer programming and drawing. |
