trying to work out the definition in the pdf something gone wrong
Moved to Grasshopper category.
it is good to internalise data, it is more simple to help.
Right click on component
Pipe needs curves not points. Then you can put a slider to understand how edges are ordered. For me 1 and 3 is good.
I advise you to put slider on each index in order to control all components outputs, then use
to see just selected component so you’ll be able to better understand what you do and not just copy a definition.
