1, draw the upper and lower contours.
2. Converted into a multi-segment line with a fixed number of segments, and the values are unified.
3. Change the number of segments to 1 so that there are no segments in the vertical direction, and choose to generate only the longitudinal lines of the surface in the geometry.
4. Using staggered model, first draw a reference surface and draw irregular line segments on it.
5, keep the line segment, and then pull it into a plane with vertical lines staggered.
