| Abstract: | According to the helix theories of cylinder, the essential factors of helix with torus are analyzed, and the parametric equation of helix on torus is given based on analytic geometry. The mathematical model of ruled helicoids on torus is constructed and two expression methods of ruled helicoids are discussed. The projective view and 3D solid view of helix on torus are drawn by AutoCAD VisualLisp, and the method of 3D modeling about vertical helicoids and oblique helicoids is given. |
