There is a helpful “topology” node that helps label various aspects of a brep before it is unfolded. See attached screenshot and attached file.

Just show raw point information and face info.gh (19.3 KB)Is there a way to generate similar labelling for at least the **faces** of the flattened version of the brep? I realize there would not be an identical function for the points or edges, since there number increases through this flattening operation.

I have enjoyed using the “label” feature of the unrolled surface command in Rhino but I have not found any similar functionality in Grasshopper…except for the seed of it in this topology feature. I would like to expand the previous Rhino unrolled labelling to include dihedral angles (see sketch below).

Labelling the new individual flattened breps and coordinating these with the faces of the original brep seems like a good place to start with all this. Any help with helpful nodes is greatly appreciated.
