The invention relates to a transition molded line lofting and smoothing method. The transition molded line lofting and smoothing method comprises the following steps: A1, making opposite extension lines at a first transition end point and a second transition end point respectively till the opposite extension lines are intersected with reference to line characteristics of molded lines to be transited; A2, making a circle by taking an intersection point as a first circle center and taking a distance from the first circle center to the first transition end point as a semi-diameter; A3, making an arc segment tangent to the extension lines between a first tangency point and a second tangency point by taking the first transition end point as the first tangency point and taking an intersection point of the marked circle and the extension line of the second transition end point; and A4, taking the arc segment and an extension line segment between the second tangency point and the second transition end point as filtration molded lines entirely and smoothing. According to the transition type line lofting and smoothing method, initial connection lines of the transition molded lines are changed from being marked subjectively in the prior art to be marked accurately due to the normal geometrical drawing connection manner, so that the process of lofting and smoothing the transition molded lines is stable and controllable; the smoothness and the reliability are improved.
