Sorry, I don't know. Using the Sheet metal functions in high end CAD systems it seems that the flattening is something quite elaborate. Intresting question.

Gerges Youssef

Using Solidworks can help you to get the flattened sheet metal geometry easily.

I would like to study the implementation/algorithm, so ready functionality made available for a user would not help.
