Made a first test of an Exel component (PointCoordinate Extraction) which works really well. As Grasshopper seems to rerun the code when a change in the logic is detected it even works live!!
http://groups.google.com/group/grasshopper3d/web/grasshopperExcel.mov http://shift-lab.blogspot.com/ Creating a bidirectional component is a bit harder as one would have to write an event watcher for Excel to make the Excel-> grasshopper direction possible... Any ideas for that? Marc
