The invention discloses a method for drawing the expanded view of a right-cone-shaped tank. The problems that an existing drawing method for drawing the expanded view through a geometric method is low in efficiency, and the expanded view drawn through a cone frustum approximate expansion method is not high in precision are mainly solved. Expansion data of the right-cone-shaped tank are fast calculated through excel software, and the expanded view of the right-cone-shaped tank is drawn through a compiled AutoLISP program in AutoCAD software. Data calculated through the method are obviously more accurate than existing data with a cone frustum approximately expanded, and compared with the existing drawing method for drawing the expanded view through the geometric method, efficiency is improved greatly.
