When the object抯 axonometric drawing is drawn, the axonometric axes ought to be determined according to the characteristic of its shape. As its axonometric drawing is drawn, so its oblique stereograph is drawn. An oblique stereograph consists of tow oblique drawings. Determining the oblique axes and the axial coefficient of foreshortening of the oblique drawings in an oblique stereograph is the hinge, drawing an oblique stereograph. This paper introduces a method to determine the oblique axes and the axial coefficient of foreshortening of an oblique stereograph and gives a piece of stereograph. And it explains the position of the oblique drawings in an oblique stereograph that is viewed by different means.
