generative modeling for Rhino
Hi Leslie -
Glad to see some other Cornellians active on the board :) When I got your email believe it or not I was already composing a response!
If you follow the instructions on this page exactly: http://dimitrie.wordpress.com/2009/05/01/3d-voronoi-in-grasshopper/, the one step that remains is to right-click the qhull script component, choose referenced assemblies, and then REMOVE the selected assembly from the list.
If that doesn't work, try the attached edited version of the script component. Just make sure you update the Path to wherever you downloaded qhull.
