Hi bz,

> Is there a way to unwrap a surface in MoI ?

Sorry no, MoI does not have any unwrapping functionality itself.

Unwrapping is a pretty complex topic, there are various different approaches and doing a real surface "unroll" is only possible with developable surfaces: http://en.wikipedia.org/wiki/Developable_surface , which means the surface has to be constructed in a specific constrained manner.

What are you trying to do with the unwrapped results? If you can give some more information I may be able to point you towards other tools to use in combination with MoI which could help.
