Hi Michael,

Many thanks for the tips. I'm going to have a go at this over the weekend if the boy will give me time. I'm going to try to do this initially in a developable way I think, more in keeping with the actual material. My thinking is that a hull is basically a cylinder shape at midships and various tapers or cones towards bow and stern, trimmed to conform in the horizontal plane (that probably didn't make any sense either!). I will still have to do the unfolding from a polygon model as I don't have access to Rhino. Even so, I'm guessing I'm going to get a cleaner unfolded shape by staying as close as I can to a developable surface.

> Not in a fully general manner - for example there is not any kind of "force to be developable" checkbox that you can set.

Would such a check box be a possibilty for a future version of MoI?
