| Abstract: | Using the method of circle arc projection to solve the problm of relative location of taper curve and other spatial geometric elements can make drawings simpler and preciser.This essay further proves and discusses the conditions that a new projection, after which the quadratic curve is projected through a cirde arc, becomes a straight line. |

| Keywords: | Circle-arc project projectionary axis quadratic curve |
