This is the final result you will get when accomplishing this task:
Load file "GM_EX_02.e3" and start the Advanced GSM command. Now proceed as in previous example "Matching an initial and a target curve, preserving another one".
The only difference is you now have two groups of matching curves. So, while you still preserve the green boundary curve, the first matching group is composed of the blue curve along the surface (initial) and the red one above:
The second group is composed of the blue boundary curve and of the red curve above:
The result you obtain is the following:
