| Abstract: | On the base of imitating firing correspondence principle, length and direction of long axis and short axis of the ellipse shaped in inclined axis measuring projection by projecting of circular parallel to coordinate surface are discussed. Furthermore, according to results these ellipses could be drawn expediently using ELLIPSE in AutoCAD. |
