How do you unroll each polysurface from their common face? The goal is have each triangle cut out with their respective rectangular flaps still attached to them. Any help is greatly appreciated.

This will not unfold without overlapping.
Working on it…
Here is a start, adapting code from the other thread.
The white group orients the triangles to a grid. The gray group moves the original geometry out of the way, though I probably should have moved the grid instead,
The flaps are always rotated 90 degrees, even though they are not always 90 degrees from the triangle surface… 
That part still needs to be fixed.

Ah. I misunderstood. I thought they wanted the faces abutting each other without the flaps.
Fixed flap rotation. That was almost too easy! Moved the grid too.

Thank you, the unroll polysurface component was not able to work as desired, so this really helps.
