Hey Guys,

for production of glass molds, I need to know how many different molds I have to shape. In other words, I want to find out, which of my double curved surfaces are identical. Does anyone know how to do it? My idea was somehow to compare the minimal principle curvature and its direction, the maximum principle curvature and its direction and the area of each surface in my list, to all the other surfaces in the list. But I dont know how to perform this with grasshopper. Is there a mathematically an easier way to see if two surfaces are identically, with less then 5 parameters to compare? And how to do this in grasshopper?

I will attach my surfaces

Best regards

Paul
