The invention discloses an establishing method of a novel two-dimensional tower editor and a tower modeling method. According to the tower editor, objected-oriented programs are adopted, various tower attributes are abstracted, a virtual base class tower description attribute and method are established, different types of tower description files (.XML format) are derived, and the parameters of a tower model can be calculated automatically by visual editing and tower instantiating. The establishing method of the novel two-dimensional tower editor and the tower modeling method are mainly used for lightning protection performance analysis tower modeling work of an electric transmission line so as to improve the lightning protection analysis modeling efficiency of the electric transmission line.
