Convert compound surface to flat surface pattern

I have a surface that curves in both directions. It is ratherlike a section of sail on a sailboat. This section of sail wouldhave curves that have been projected on the surface, let's say thatthey are star shaped. I want to develop the outline of the starshape when it is cut out of 2D cloth.

Does anybody have any ideas on how to go about this?SolidworksSurfacing
