Select the two edges to match.
In the App Options panel, click U, V Orders .
The orders of the element appear along the U and V directions of the

Shift-clicking goes up in the list.
The Automatic option enables you to modify the order and the
segmentation of the matching surface to respect the continuity. The surface
order is instantly modified. You can see it by using the Control
Points option.
