i´m looking for a way to unwrap or unfold polygons from 3d space to 2d plain,
more or less than this processing library, but instead of triangles it should work with any n-sides polygon.

thanks for the answer,
i know Pepakura and there are other tools in the market, also is possible to do the same in 3Dstudio with the unwrap UVW tool, but i don´t really need the folding net but every polygon points folded into 2d and translated to (0,0).

In Autocad there is a tool called “Align” to align any arbitrary polygon in the 3D space to the 2D plane, in order to obtain the real dimensions of a 2D object.

I think it could be possible in vvvv calculating the polygon´s Normal vector, and then fold it in 2d plane using it as reference, but for now it´s out of my math skills.
