How to make a "3D->2D ready to cut" drawings ?

There is a yahoo site:

Did a quick pretend model with the catenary script, offset, rotate, mirror, loft, lineweb, isocurves, and unwrap curve to get the blue lines.

You can "unwrap" curves, to a straight line, but MoI does not have "unwrap surface," as far as I know.
