Hello! Does anyone know how to do it into panels?
The problem is that your sub-surfaces aren’t planar, which makes derived geometries (e.g. scaled edge curves) also non-planar. You could try to planarize your brep faces with Kangaroo. There are many examples on how to do that floating around. However, I suspect that this will alter your overall geometry drastically or won’t be possible at all for this geometry.
thank!
