The cubic in an isotropic plane which passes through the intersections of the sides of an orthic triangle with the sides of a complementary triangle of a given triangle, and through the point which is complementary to the Steiner point of triangle is studied in this paper. It is proved that its non-isotropic asymptote is parallel to Lemoine line of a given triangle.; U članku se proučava kubika koja prolazi kroz sjecišta stranica ortotrokuta i komplementarnog trokuta danog trokuta i kroz točku komplementarnu Steinerovoj točki tog trokuta. Dokazuje se da je neizotropna asimptota kubike paralelna s Lemoineovim pravcem danog trokuta.
