To create a box pleat, you will need a selection of 4 points, which will define the pleat width.
The first point and the second point selected correspond to the first pleating line, while the third point and fourth point correspond to the last pleating line.
After a valid points selection, the lines for a double pleat with the under edges folded toward each other are created on the piece.

Note! A point valid selection is when the line that joins the points 1 and 2 does not intersect the line that joins the points 3 and 4 and when the lines intersect the piece contour.
