Dear Rhino/Grasshopper developers thanks for Rhino 6, many useful improvements, render, Rhinocommon functions … but there is an old subject Polyline Offset see this thread : [image] We need to talk about Offset As a collective can we find a way to overcome the pitfalls of the current inw…

Thanks for bringing this up again here. It’s been bugging me quite regularly as well.
