| Abstract: | This paper starts from the analytical equations of generator of quadrics,works outthe envelope line of family of curves,and sets up the curve equations of conicoid visible line innormal axonometric projection and generators of quadrics by analytic method,and also draws outthe figures by computer.These analytical equations are applicable to all orthographic axonometricprojection in any direction. |
