An updated version of this tool can be found in the PCPA_GH plugin
This is a set of three components that exposes the sticky library of GH in the graphic interface. The sticky library is a temporary place to store data so user can manage design options without baking everything into Rhino model. Another way to look at this is that it breaks down many evolutionary solver algorithms into manual steps for finer control. Beware that the temporary storage will clear after GH is shut down.
The components are written in GhPython for Rhino 6. They are in beta testing. Watch the demo below to see how they can be used. Simply put the StickyIO.ghpy in the Grasshopper library folder. Make sure you "unblock" it first.
