You draw the line on the left image, which makes the same thing appear
on the right image. Then you highlight the new line that appears in
the right image, click the button to adjust it, and then move the line
around using the boxes, until you get it where you need it. Then
highlight the left image again, and click to associate. Always
associate left to right, as you're morphing from the left image to the
right image.
Hope that helps.
