It is a beginner level inquiry, however, any sort of help is highly appreciated.
In grasshopper, how can I define the surface numbers of all the breps in such a way that all the common surfaces have same number. Also, can you please give a scripted example.
Deconstruct the brep, calculate area of faces, then cull duplicates (the centers) this will give you an unique list of indexes (centers so faces) and points
