Is there a Rhino 3d Sheet Metal Plugin around?

Hi there, sorry if this has been discussed before but I would like to ask if anyone knows of a good Sheet Metal Fabrication plugin for Rhino or a script with the ability to unfold geometry (like the current unfold operation in Rhino) but with optional bend tolerances and material assignment and properties and so on?
This might seem like a tall order but its worth a look see.


There website is not updated for a while, but have a look at:
Lamina design

It might do the job.

Cheers Kev.
