haha I 've saw your this nice answer days before and downloaded the clean sample!
Thanks a lot for your prompt reply. In fact I’m working on research and the main practice is on matlab and python(for data exchange and visualization), that’s why I haven’t any knowledge on C#. So for primary modify of data structure, the ghpython is enough, until now… The C# learning curve is sooo…
So @piac can this function work on ghpython? Is there some more deep tutorial on python beyond this?
