Hi Youngken - Use SrfSeam to move the seam to your cutting line, assuming it lines up, then UnrollSrf.

Hi Pascal,
After unfolding, I want to know whether the isocurve is divided by angle (45 degree) or not?

Hi Youngken - I have no idea but Iā€™d think off hand that is very unlikely, unless by chance. You can test by adding lines every 45 degrees and unrolling with the surface.
